Hi,

I just started my first conversion of a Poulon 25cc with a Zama carb.

I'm attaching the pictures from this weekend's activity in the hopes that it helps someone else on their "first", and to provide some context for my questions.



The next pic is of the disassembly of the muffler and pull starter removed.



The next pic shows the length of the drive shaft - it's about 4 inches long. My question is...should I cut it down or leave it and machine the prop hub to match the length? Not sure what plane I'm putting this in so, that may have an impact on the decision.



If anyone can help me on the drive shaft length question I would appreciate it.

Thx.

Scott
