Stihl 311y????

[50blues]

Well a couple of days ago, I had a 311y (why) the heck do I have this. To a 024. Measured the stroke, kind of hard to get a good measure, but I never had one over 30mm.

So I have a 024.

Thanks for all your help.

If you have an adjustable carb (has H & L needle on the carb) you can open the muffler and gain a fair amount of power. It is certainly worth discussing. It won't harm your saw in anyway and can actually let it run cooler.

I measured out my 024 super tonight and it came right out to 32mm. Never thought of measuring stroke like that. Rep all around.

Yes, its an 024. Now trying to determine if its a super is the tricky part. If the con rod is stamped I'm pretty sure its a plain 024. If its cast then its a super. Anyone else have tell tale signs of determining the difference?

Btw my apologys to the member I was busting on about using the search feature.

It SUCKS

If I remember correctly 024 Super/Wood Boss and the 026 have a caged rod bearing on the crank the 024AV doesn't.

this one I think is an 028 super

or 034?

As stated before in this thread if the part number starts with a 1125 its either an 034 or 036. 034 has a 46mm piston 036 has a 48mm piston. Probably a 034.

or 034?

034 etc fits with the part numbers starting with 1125....
