The 361 is done and a fraction of a second behind the 360 in cutting times. The 962 is on hold awaiting a new piston. It ate a stray washer. Brian can fill you in on the details.

New piston is in for the 962. Should be in the mail on Friday. Looks like a 165 piston would work but ring pins are in a different place. Will put up a pic of the 2 tomorrow.

962 piston on left, 165 on right. Only difference is in ring pin placement.

Nice looking pistons (to the eye in a pic).  Are both skirts same width?

On a side note, Brian could fix the pin issue if it had to be.


So the only difference in 962 and 165 is the cc of the large looking combustion chamber on the 165 and off set c.c. or is the porting stock different too?

The 165 has a 1mm longer stroke, and different upper transfers. The 962 is like a 200 series Husky. Upper transfers on the 165 are like the 300 series.

I think a 962 cyl on a 165 case should do good. If rod length is the same.

Any updates on how the 962 compared? 

Art are the bore and strokes the same on 962 and 165?  What is the difference, cylinder?

Brian said that the 962 should be back together this week. He dropped a washer into the crankcase on assembly and it ate the piston on startup. He has the new piston now.

962
61.5cc, 48mm bore, 34mm stroke

165
63.4cc, 48mm bore, 35mm stroke
