Another 024/026 thred...oh goodie..

Alrighty,

I've got what I think is an 024AV. Model number on the side of the piston is 42ZN12....which I think is an 024 jug (42cc). if it were an 026 it would say 44 instead of the 42. My question is, I'd like to resurrect this turd as an 026 as I've already got a decent 024AVWB with a 16" Stihl bar & chain (whoopee). I know the 26 has a longer stroke, and the serial number on this saw's case is 217303683. Is this saw/case late enough that it'll hold the crank (as the 26 crank "has larger journals" I'm told)? I'd much rather turn it into an 026. Any and all input and assistance is very respectfully appreciated!

Thanks,
JS

If you have an 024 super you convert it to an 026.

Ok, thanks for that answer. Been wondering whether or not it was do-able to up grade the crank, rod and top end on a 24 up to a 26.

Thanks again,

Bottom line Is clearance. If it has it it will work like a charm. I recall a little something being differences somewhere but the crank and rod were not it. Check Back I could be wrong. Did the larger have a decomp. Valve?

Yes, the 026 is supposed to have a decomp valve

The early 026 did not have a decomp valve... The later ones did.
