I destroyed my original needle when I overhauled a badly neglected carb. from my Puch MK II.
I got a new needle for my carb, but I don't know which notch to attach the washer to (there are four notches).
I tried the second notch from the top. The moped runs great, but tops out at around 25MPH, which seems slow (although I don't know if it actually is for this moped because I never had it running until now).
It is a 1980 Puch MK II, 1.5 HP engine. Shouldn't it be going at least 30 MPH? Would the needle position make a difference? My intuition, which could be wrong, tells me that moving the needle up more, so that it is on a lower notch, would introduce more gas into the engine.
Thanks for your help.
