I got this 1hp Puch Maxi recently, and it's running strong - just really slow!
The carb was really corroded and stuff - so for testing purposes I put a brand new 15mm carb on it, and it's still going like 20mph. It's somewhat loud, kinda rackety, and it knocks a little. There doesn't seem to be an air leak anywhere (anymore at least). I tested compression on it, and got 120 - is that good?
Is this timing / points do you think?
Fixed air leak issue
Cleaned cylinder and checked rings
New spark plug
I hope this thing isn't supposed to be going 20. I measured the rear sprocket, and it's the same size as my Newport (which does not go 20)
