Sachs Dolmar conversion upgrades
 

Hello,
I replaced the piston,ring and wrist pin in my Sachs 3.1 conversion today. The new piston has a gray color. Could it be graphite? I also installed a Walbro HDB 6B 15.88mm carb off a pro mac 610 saw. It has a 3/4th inch throttle bore and requires a spacer between the manifold and carb.

Hi Ken,
That's good to know. I don't think that there will be any of the incoming charge traped in the piston. Is your piston dark graycolor? The 3.1 came stock with a 13.49mm carb. What size carb does your 3.3 have?
