Title: mako piston/cylinder for stihl 036
Post by: brokenbudget on January 04, 2012, 12:46:57 pm
i'll let the pictures speak for themselves ;)
ordered this topend from the local stihl (yep stihl) dealer. total cost was just a hair over $200. the oem was almost $400+tax for the same parts.
the saw is an old 56cc 034 i have had around since the late '90's. has had alot of wood put past it and has been apart so many times it's funny. so it's the perfect test bed for any of these cheap parts i like trying to make my own opinion about. this mako topend? for just the visual quality, thumbs down.
the piston is crude, plain and simple. but the machining is good enough for the 'put it together and just run it' crowd. (as i am doing with this topend).

the wrist pin is a little too easy to insert, so i used the original. you will need to use the supplied clips as the new pistons grooves are too big for the stockers. new one on the right.

the cylinder leaves alot to be desired in the quality department. it has big castings, rough transfers and crude porting. notice the exhaust port. total rectangle with no room for useful improvment. may be a ring catcher, but we'll see :D

notice no ring support in the intake:

notice the combustion chamber? how do you let it get packaged up like that? crude crude crude >:(
(http://i39.tinypic.com/35m1e69.jpg)

not a great pic but the 'white' area is extremly rough. like gravel road rough.
(http://i44.tinypic.com/359msxw.jpg)

the rings look like the split ductile units supplied with the nwp units. nothing special.
(http://i42.tinypic.com/akae8g.jpg)

how does it run? it runs o.k.. nothing to write home about and the compression is abit over 145 psi. it started out with 135psi. ::) the squish clearence is just a touch over 40thou. you can't shave much off the bottom of the cylinder, you'll free port.
we'll see how it holds up with regular cutting duties and abuse. i have it tuned a bit fat at 12500.

you need to cut some of the top covers reinforcment out.
(http://i43.tinypic.com/30ubs08.jpg)
you also nee to cut half the rubber bumper to fit past the fin on the cylinder.

crap! i thought it wasshown in this pic ;D you get the idea ;D

Thanks for the pics on Mako. 

I still cant believe the cost you had to pay for AFM kit up there.  :o

i'll be sticking to the kits that bailey's supplies. they are by far the best ones out there right now. i wanted to try one of these mako kits out as i have heard pretty good things about them. guess the people who have bought them and thought they were pretty good need to have their eyes examined. or buy other kits to compare them too. :) maybe i just got one of the 'made on friday' kits ;)

OOOOOH YEAH! the 034 gotsed a new airfilter too 8) it's been getting more and more balled overtime, figured it's time for less dust injection ;)

i would've showed you how nice the cylinder was and the lack of any scratches and polishing it had. but when kristian returned it. it looked like a thissss:
(http://i39.tinypic.com/2v9rz8l.jpg)
this is what happens when a fuel line goes bad, the person is mostly deaf and has almost no feeling in his hands.
he felt awful about it. wanted to just buy the saw from me or atleast pay to have all the parts replaced plus my time. his saw (034 super) was at my place getting a new line (coincidence?) and a carb rebuild. scared him when i said i was keeping his saw (it's freaking mint and runs fantastic). i told him i should have cought the problem as i was the last person to run the saw 3 or 4 months ago, seemed o.k. then but it's a long wait for a saw. and i even gave the saw a look over and run before it went out the door. ::) not his fault in my head. he wouldn't run a saw he thought wasn't running properly. he said it didn't give any indication of any problem while running, just when he filled it up and gave it a tug. said it felt a little soft on the pull cord......
i ain't charging him anything. this guy is a top notch borrower, will always step up if something is his fault (even when not), and i'll happily lend him another saw if needed.
i've had the saw since '94-'95 or so, came to me in a box with a toasted topend after a 'contractor' tried to run just one tank of straight fuel to get one last cut out of it for the day. it looked almost like new then... the saw, not the piston ;D
if this piston/cylinder doesn't work out, i'll probably order the bailey's nwp kit to try. :)

i've dealt with them before and they are pretty good :). problem is (for some reason) it takes quite a bit longer for their stuff to get here. almost 2 months compared to bailey's 1 month. may not be their fault, could be customs and canadapost farting around. :o

it's just the luck of the draw for some people. :) i wasn't even close to being disapointed, just an oh well, perfect time for some experimenting :D

 :D i have no idea why the muffler bolt holes look like they are stripped out in the pic, ;D

well, it seems the quality of their product is reflected in their customer service. ::)

"we're sorry to hear you're not happy with the quality of our cylinders. we appreciate your feedback and will look into
your comments.
mako products are now sold in 37 countries with incredible success, this is why we are suprised by your comments but appreciate them
at the same time.
as for the price, we believe mako products are the most competatively priced products on the market, but we cannot control the retail price our customers set.
thanks for the feedback, and sorry the product didn't meet your satisfaction".
adam.

so, when a customer sends you pictures of an obvious problem with quality control, you send them an ad vert as a response? nice going jakmax. i've had better dealings with suppliers out of china. better quality also. :o
if anybody wants to see the full email i sent, just pm me. i have no idea how to post it here. :)

Customer service probably has no idea what a good cylinder is supposed to look like anyhow. You could have showed them a pic of a clutch and they wouldn't know the difference. ;D
Title: Re: mako piston/cylinder for stihl 036
Post by: brokenbudget on January 10, 2012, 06:57:45 pm
your probably right! :) except the clutch would be far better quality than their kit :D
the response i recieved sort of makes this page of their site meaningless: http://www.jakmax.com.au/aboutus/index.php  ::)
oh well, keep tossing crap like this in a box and word will get around. eventually.

well, after a month of use, and lots of fuel (can't remember how may tanks ;D), the saw is still running and making pretty good power. i would have to say it is making the same ommph a regular 61.5cc 034 would make, and quite honestly, feels like a little more. starts easy, good on gas, great (yes great) throttle response and likes to rev 8) i have it tuned way up to about 13800 rpm, still burbles nicely and the compression has come up to just under 155psi. not bad so far :)
now the problem is getting it back from kristian long enough to give it a good go myself. ;) i have a pile of crappy manitoba maples out back that need to be removed so i can get the old farm equipment out of there ;D

Post by: Cut4fun . on February 11, 2012, 02:51:08 pm
So now for the big question, if you had a choice of a Mako or Golf piston only which would you choose?

Did you use the Mako rings, pin and circlips supplied?
Title: Re: mako piston/cylinder for stihl 036
Post by: brokenbudget on February 11, 2012, 03:29:06 pm
the only thing from them i didn't use was the pin :) it was a little to easy to insert it into the piston. the clips are also bigger than the stock pieces, so you need to use them. there wasn't any problems with getting them in and they fit properly. not too deep in the groove or easily bent out of shape.
i would like to see what this would run like with a stock piston in that thar cylinder :) but it seems to run very well the way it is.
Title: Re: mako piston/cylinder for stihl 036
Post by: Cut4fun . on February 11, 2012, 03:41:17 pm
LOL so if you had only 2 choices. Mako or Golf piston which would you use?
Title: Re: mako piston/cylinder for stihl 036
Post by: brokenbudget on February 11, 2012, 04:08:21 pm
go golfing dude! ;D their quality can't be beat!---most of the time :D the casting and machining mako passes off as 'good enough' (at least in this kit), leaves you wondering if 'fugly' can slow down a saw :D
every golf piston i have had in my hands looked fantastic compared to the mako unit. some even looked better than the stockers did. all new pistons usually look better than a piston that went thermo-nuclear ;D

Meteor is my 1st choice in AFM. But unfortunately it isnt offered in 246.  ;)

i have nothing but perfect success using meteor pistons :) they have their reputation for a reason!
HOWEVER! the last 2 i recieved were a little less nice looking. lots of casting flash up inside. nothing that would hinder performance, but maybe add a little weight and a possible starting point for fracturing. they were sent back and replaced with perfectly fine parts.

I like the Episan pistons also. I think they are right there with meteor quality wise.
Title: Re: mako piston/cylinder for stihl 036
Post by: brokenbudget on February 12, 2012, 10:35:08 am
episan has been good quality for a long time :) used them for the slowmobiles as they were one of the lightest aftermarket pistons out there. held up WAY better then any wiseco i used in the same place. they seemed to take the rpm's better and not loose a skirt like a wiseco. actually, most of the polaris engines i put wiseco's in would get about half a season before ruining a good bottomend >:(
i won't touch a wiesco product anymore. i find it funny that even the kimpex pistons would hold up better than the wiseco's. and they're the cheapest replacements out there for a snow machine :D

Thanks for the review on the Mako P&C have been curiuos about quality.  I just did an Ahlborn BBK for Dol/Mak 6401.  I was very pleased with quality.  I thought it was better than the NWP BBK and my cost was $80.00.  Asked John where their pistons and P&C kit were made he said Tiawan.   Just put an Ahlborn piston in a MS 460.  Very little casting flash in windows took me more time to change bits than it did to smooth things out.  Very pleased with fit and finish on this my first Ahlborn piston.   Neighbor dropped a tree on his low hr. 034 gave me the carcass.  Have been able to salvage but too many fins are broken off of the cyl.   When I get to it I'll order an 036 P&C from Ahlborn under $90.00 Nikasil plating.  Hope it's as nice as the BBK.  The problem with Ahlborn is ship cost MS460 piston $15.50 + $5.00 handling chg. + ship Fedex $12.00=$17.00 shipping.  I will complain the next time I order.  Really PO'd about ship cost.  Their fuel lines are junk had problems with 2-MS290 would not seal in the tank.   2-026 pulled in two.  1-MS460 pulled in two 1-too lg. for tank had. a heck of a time getting it to seal.

This Ahlborn you are talking about is those Forester kits they have listed in their catalog then?

Have you tried their yellow fuel line or the rolls of black?  The yellow looks like a Tygon copy but clearer yellow.

Have been using some of both the black and yellow.  Haven't been using either one long enough to pass judgement (6months).  Using yellow for the tiny one for weedeaters. Black for the rest.

Have you noticed the line you have used getting stiff or not pliable?  The clear and clearer yellow I have used in the past hardened up in a years time.

Never tried the black or yellow roll listed there yet. Will wait on your experience and feedback down the road.

Least now I know to stay away from their molded lines. Thanks for info.

Post by: brokenbudget on February 16, 2012, 06:58:36 am
i use that yellow stuff from oregon. seems to stay pliable forever and doesn't shrink or turn to a black goo :)
i've also used windshield washer tubing. it's made to carry methanol. the only problem i have encountered is now they seem to be adding a sort of strip of rubber (like a mold line) along the side of the tubing. makes it harder to have it seal.
