Has anyone done this? Seems like it could be done fairly easily. Surely someone has done this back when those saws were first coming out. I had a pair of old 024 builder saws and I've got a pile of 028s of every sub model. The 024s both needed a new piston and cylinder. Both were 42mm bore if I recall correctly. I had on hand from the 028 super a good OEM 46mm top end. The 024 uses a 1mm longer stroke then the 028 super. I believe the result would be roughly a 55-56cc 024.
The cylinder bolt patterns are the same. It looks like the 028 could be modified to work on the 024.
The 028 piston skirt is way to long. It hits the case and crank counter weights. I chucked the piston up in the lathe knocked the skirt down so it clears now.
Still not sure if it will even work but with very minor cooling fin and cylinder clearancing it will bolt right on now. Over the weekend maybe I'll have some time to mess with it.
Surely someone have gotten this work. I searched and couldn't find any info on it anywhere.
