Title: 024 rebuild top end
Post by: leec on April 23, 2018, 08:32:15 pm
Working on a 024 and have many questions.  One question is how does the muffler attach? it seems to have very short bolts but the muffler doesn't appear to open up so you can get at the bolts. ??? The saw came to me missing a number of parts, muffler included so I didn't get to take it appart.

There are 2bolts that go in the bottom of the muffler and cover that thread into the crankcase. The muffler and cover slide together at the top. Pry out the cover at the bottom near the bolt holes and wiggle and pull down and they should come apart. That will give you access to the inner bolt holes the attach the muffler to the cylinder. Hope that helps and is not as clear as mud.

026 shows the muffler too. I have the same muffler on the 026 I just rebuilt, I think.  Just like jmester says to do it. 

Mine is the middle one and now opened the single hole up to one big oval. Makes a different on these IMO.

Next question, what does the air filter cover lock onto?

 Air filter cover locks into the air filter if like the 026 I had.

Just now waiting for my parts order to arrive.  It seems a few very small bit missing, grounding spring, 1 spike bolt, 1 recoil bolt, fuel tank vent.  Annoying really these parts are cheap but shipping kills it

That cover above in my 026 pic is left over if needed. The guy went with the decomp and decomp 026 cover I had.

My first order from Huztl has arrived.  This one has P&C, muffler, clutch cover and af cover.  And a few small bits.  I had to go to a Stihl dealer to get replacement muffler and cylinder bolts, paid more for them than the P&C from Huztl! Something very Stihl is they have switched from allen head bolts to Torx head bolts of T27 size, very hard to find in my neck of the woods.

So just sent my third order to Huztl as I'm not a Stihl guy so missed some needed bits and pieces.  The last one was the piston wrist pin roller bearing, certainly won't run without. So the wait goes on.
Pretty impressed with the Farmertec cylinder, comparing to the OEM (which is toast). Oddly Huztl didn't seem to list a fuel line for the 024?

Just for general info .Those torx head metric bolts are about a buck a pop at a Stihl dealer .You can order them through Northwood saw for about 1/4 that .I usually buy about 20 at a time .The web site is little tricky to navigate but you can find the size if you look long enough  .Fill out an order form on line then confirm and pay for it with a telephone call .

Speaking of those Stihl torx head screws, I just changed the upper right hand spring mount on my Husqvarna 562XP.
 Used a Allen head wrench to get the old mount off, but with the main screen  embedded inside the new spring the darn thing wouldn't screw in with the Allen head.
Low and behold it was a torx head, not sure if it had the Stihl type lock teeth though.

At any rate Husqvarna should not stop there with that one screw....replace them all ;D

I was not aware Stihl used serrated head torx screws .They did however use serrated belleville type washers though on some models ,namely 200T muffler bolts

Just waiting for the wrist pin bearing and a fuel line on the 024.  Once together I'll need to look for a bar and chain, probably 16" .325 x 63. After looking all over town for a long thin T27 my local Stihl dealer gave me one that looks like an allen key, FREE.

Crappo! I ordered the wrong P&C the one for the shorter stroke engine so I'll order again.  Might as well go for the 026 P&C, it'e longer shaft and bigger bore than the straight 024.  Mine is a 024 Super with the longer stroke. Drat!

So finally got all my bits; 026 P&C, decomp, etc.  Had a hell of a time getting the rubber bellows onto the cylinder intake. Saw would not start. New filter and line carb set 1 1/4 and 1. Not sure about my comp tester but only seemed to get a 80 psi. Chinese de-comp leaking as well as the oEM fuel cap.  replaced those at my local dealer, didn't want to wait another 4 weeks.
 trickled some fuel into the carb and it started Actually just sealed the decomp. not really needed on a 47cc saw.

The AF that came with this saw doesn't the tab the the AF cover latches onto so it remains loose.  Have to get a different air filter.

Huztl top cover not a great fit without tweeking and sadly no place for the nice Stihl Super 024 plate.

I have a Huztl P&C for a standard 024 if anyone needs one.

I have an old solid nose bar from my o31av but need a .325 chain, although I guess I could run the 3/8th on it with a new sprocket

Help Needed

Saw now wont start so ordered a new carb along with the proper air filter with tab. So how does the carb come off? I can't seem to manage to disconnect the throttle rod which is holding the carb on the saw. Almost the same price as a carb kit!!!

Post by: leec on September 22, 2018, 10:20:56 pm
OK folks I got it figured and new carb installed too late to test.

OK dumbo here. Top of the rear handle comes off to release the throttle rod.  New carb and and it's running just fine .  Need to get a bar and chain then off down the road it goes.
