thanks for any help updating or expanding the list . somehow had it in my head plain text downloadable format might be easier to print.  I am about to advertise locally for stihl parts want a printed list ready when they call in with a model  I never heard of.

If you order a engine or short block look it over carefully. I filed off flashing all over outside of 025 engine. still had to grind muffler T slot  bolt to make it work. That said  huztl is a great help on saws missing bar cover or recoil or plastic covers and such. Can be all the difference in profit and loss on old saws missing parts.
Title: Re: huztl cheat sheet
Post by: DefinitiveDave on October 11, 2015, 08:44:02 pm
I stopped selling the short block as I had 6 pistons detonate because they were too long inside the crankcase and were hitting.
We swapped the cylinders out for the FT big bore and they were fine but made me nervous so I stopped selling them.
Dave
Title: Re: huztl cheat sheet
Post by: dannyupsolate on October 12, 2015, 11:27:22 am
were the 660 cylinders too tight in the squish or am I misunderstanding
Title: Re: huztl cheat sheet
Post by: DefinitiveDave on October 12, 2015, 01:24:48 pm
piston skirt on the piston that was installed on the complete engine was too long as best we could tell, we measured it against all the other types of 066 pistons and it was taller overall with the additional height being below the piston pin
I told Farmertec about the problem and I replaced those 6 cylinders with FT BB cylinder kits which Farmertec sent me free on my next order.
they are normally good to correct a problem but it made me nervous to use this kit at all

this is why it is safer to order from Dave
Title: Re: huztl cheat sheet
Post by: DefinitiveDave on October 13, 2015, 09:04:04 am
crazy thing was when we tore 2 of them down at the same time on my bench and really compared things, the complete engine from FT did not have the same cylinder and piston as the standard bore of each that they sell as a standalone part
I am 99% sure they don't make their own crankcases, maybe they bought the complete engine in from another vendor to resell?
its that kind stuff that makes head scratching a going concern

This inconsistency when dealing with Huztl is what's so scary. One guy made up a 660 from Huztl parts and the starter assembly was junk but everything else was excellent. It was all bought at the same time.

Dave, I'd like to try a couple 036 tanks. Any ETA on more?

Title: Re: huztl cheat sheet
Post by: DefinitiveDave on October 14, 2015, 08:27:16 am
another inconsistency dealing in the East
placed and paid for my last Farmertec and NWP orders on the same day
NWP arrived DHL on Friday and had a short customs hold so it arrived Tuesday :)
Farmertec order still not shipped :(
though the FT order is three times the size of the NWP order in pieces and dollars so that may be the difference

Also sent my Meteor/Caber order the same day, they acknowledged receipt but no invoice yet, however they get everything boxed ready to ship before invoicing so when I get the invoice it is usually here in 4 days
Italy is much more relaxed than China/Taiwan/Turkey  it is like new your city vs. boulder Colorado :)

Thks Dave.  You think the Farmertec/Hutzl plastic (tanks) are decent quality?

I bought a bunch of China made Stihl carb boots and fuel/impulse lines recently and the quality was very nice.

Also noticed some of the new Zama carbs on ebay had the zama name machined off of the diaphragm cover and they were being sold cheap as "copies"

I have had great luck with the tanks for MS660, MS360, MS260 (except the tank vent which ALWAYS leaks, even though they sell a replacement that is perfect), MS361, MS250, MS290 (pretty damn expensive though on that model, but I consider it an upgrade from OEM actually) and have sold a ****-ton of the 372 tanks though I never used one myself.

About10% of the 361 tanks arrive with the sole-plate popped off but it hasn't really been an issue, it is there to add a little rigidity and they admit they install with three drops of superglue :)

As Stihl shifts more OEM purchase orders to shops they own entirely and away from the franchise type Zama shops I expect to see more and more of them taking custom vintage orders on carbs like the 260 and 440 that I have had done.
Most of them literally have crates and boxes of every part needed to assemble virtually any carb from most brands complete with molded logos but contractually remove logos to avoid paying a fee to a competitor of sometimes 200%.

Post by: aclarke on October 15, 2015, 09:46:28 am
Good info.  Figure that was the case with the Zama and likely other parts as well.  Someone Here or AS compared a Stihl vs AM carb boot carefully and said it had the same mold marks as the Stihl part sans logo..

Dave

So how many revolutions did it take to figure there was interference? I haven't experienced their complete short blocks, just the individual parts. Do you have the measurements from the pistons the were too long? How about some of those derelict pistons? I would like to get one and turn it into a popup.. :) (I'll trim the skirts back too) How much difference was there from stock?

(The squish "out of the box" on the 56mm kits has been in the .028-.030 range on the ones I've built so far)
Title: Re: huztl cheat sheet
Post by: weimedog on October 19, 2015, 08:44:34 pm
So I pulled 3 "white box" 54mm cylinder/pistons from Huztl out of their boxes, a "blue Box" Farmertec labeled 56mm kit from Huztl and a Mystery "White Box" 56mm from another Asian supplier.

All three 54mm pistons from Huztl were 1.69in long or approx. 43mm
The 56mm piston from Huztl was 1.61in long or approx. 41mm
The 56mm "Mystery" brand was also 1.61 although the cylinders obviously came from different molds & the pistons were of obviously different quality. The Huztl/Farmertec part has a much wider/larger cast area for the transfers. They also have symbols cast into the transfer area where the "mystery" white box special had no symbols and looks like they had corrective machining.. BUT it appears to be heavier by weight probably has more copper in the cast materials.

Meteor lists the length of their 660 pistons as 43mm, same as the measured lengths of the Huztl pistons I just measured.

The "skirt" thickness is interesting...all the 54mm skirts were in the .070in range while the 56mm was a solid .090in and exactly the same both sides.

Now I have no idea what the assembled short blocks have as I don't have one to dissect...so curious if you have a piston or two around.

My concern was actually the 56mm piston was too short with too much duration on the intake. They run strong but are harder for me to tune on the idle and low speed. I suspected the short skirt.
Title: Re: huztl cheat sheet
Post by: aclarke on October 19, 2015, 10:21:10 pm
Because of the Taper in most ports the bigger you go on a stock cylinder the more duration you loose.  Do the big bore jugs have the same port timing?
Title: Re: huztl cheat sheet
Post by: weimedog on October 20, 2015, 07:15:58 am
They aren't actually "bored" out stock/Huztl cylinders. They are a completely different casting from different molds & cores. I haven't put one on a degree wheel yet but I suspect they have different port timing from intake thru to exhaust. And combined with the shorter piston I suspect the timing is quite different. I don't know if the 56mm is a fresh design or random ... they run strong as delivered under load but I've had issues with the low speed/idle side. I suspect the intake has way too much duration for my liking. Where the 54mm use fuel at a rate consistent with a descent design, the 56mm is a bit of a hog. Maybe I'm just not used to 100cc saws.

I've got around 5 or 6 gallons of gas through these saws so far. Most through the 56mm

I have to wonder, on one of the 54mm builds, the metallic gasket interfered with the piston skirt on the first installation attempt. Took me a while to figure out what was going on. Wonder if something along those lines hurt the ones you had. At first I was thinking it was a misalignment of the cylinder bore to the case!

The other thing I found on one cylinder was a "burr" left in the combustion chamber from the tapping of the spark plug hole. That would have eventually come off and was enough to make a mess if it didn't go right out the exhaust

One thing I do know, I prefer to build my own for my work vs. trust non saw types to assemble those parts!

In your opinion will these AM part Companies make parts for more models?
I notice that more Stihl than Husky?
How about the newer X-Torq Carbed saws?

Thanks
Title: Re: huztl cheat sheet
Post by: aclarke on October 20, 2015, 04:45:52 pm
Doesn't seem like much though goes into the port arrangement/ timing on the BB cylinders..  short skirt may help with fitment into the case but, wouldn't it make sense to raise the intake floor and lower the exhaust if you were going to the trouble of making molds?
Title: Re: huztl cheat sheet
Post by: DefinitiveDave on October 20, 2015, 04:51:48 pm
As demand rises the AM companies will make anything that will sell but it needs to be along the order of thousands of pieces per month to make it worthwhile.
I will look but I am pretty sure I threw away all the long skirt pistons that I had in both individual and short block form.  You only have to sell one piece of crap to **** off a good customer for life.
I think I have a pair of the BB 660 jugs  sitting around and probably some of the pistons still in boxes if somebody wants to experiment on them.
I have not seen anything on the 500 series huskys yet from the major AM manufacturers.

Weimdog if you need parts for research let me know, I am happy to help.

Dirty little secret, guess how the third tier Cylinder manufacturers make their molds?
Yep they buy them from other manufacturers when they are too worn to use.

That would explain the "partsangle" and Wangou ones I bought to see if they were from the same place as Huztl's... they are from different molds. Probably as you say worn out from yet another mystery source... :)

Next project on the bench this week... no base gasket 54mm build with .020" popup and a muffler mod. Want to see if I can match the 56mm with simple mods. Also going to an OEM decomp. AND the pull starts had a minor issue on about half of them..:

A parts kit from "DefinitiveDave" helped and then making a simple mod to existing parts helped as well....a video documentation of pull start issue...
(Listen to that 56mm build idling happily in the back ground for those who doubt it can happen with the "short skirt"/intake duration/free port issues)

did you sand the shoulder of the pawl or the nib on the bottom to get a better action out of the pawl assembly, I wasn't clear from watching the video

I also had no idea they used different springs in the recoils than they sell loose.
thanks

The diameter of the part that rotates.. didn't take much. The ones I got from you....worked with no mods. Go figure. So the 56mm one has the sanded pawl and the 54mm's both have parts from you now. The popup version is as much of a pita to pull over as the 56mm version. You have "oem" decomps???
Title: Re: huztl cheat sheet
Post by: DefinitiveDave on November 27, 2015, 03:30:34 pm
I carry the oem decomps for the 075/76/88 etc.
I will order OEM decomps for the standard saws tonight.
I have 2 different manufacturers decomps for the standard series and they both seem to work pretty darn well, especially considering all the talk about them sucking.
2 vastly different prices but both seem to work fine.

I can get a new OEM, but there isn't much out there in the way of aftermarket.
It wont be any cheaper than your local dealer but might be faster depending on how on the ball they are :)

Thanks Dave.  I'll give bending this one back another try before I belly up to my dealer's counter.

While on the subject of decomp valves:  I have been drilling the bleed port progressively larger on this 880.

I had an aftermarket valve with a large bleed hole but the spring was too week.  Like it wasn't even there.
Title: Re: huztl cheat sheet
Post by: DefinitiveDave on April 09, 2016, 01:02:35 pm
I am pretty sure the OEM valve for the 880 has a different part number from the smaller saws and the AM valve fits the 880 but isn't the "correct" part per se.
I have heard the OEM husky valves are stiffer as well.
Dave
