So I had a stock perfectly running Puch Maxi with an E50 and a 64 jet in the 14 mm Bing. I bought a foam filter and Techno Boss from Treats and threw a 68 jet in there until I got some 72, 74, and 76 jets.
The ped went from a stock 32-33mph to about 35mph. Takes a little while to get there, but it was sluggish when it was stock too. The plug was a light tan (kinda lean). However, now it won't hold an idle, even with the idle screw in all the way.
I got my new jets and installed a 74, since it seems that's what most people on the board have done with their near-stock E50s. It now does about 35-36mph but still won't idle. Plug is like coffee with some cream, so I figure I can keep the 74 or maybe even drop down to a 72 and still be OK.
Would raising the needle a notch bring back my idle? Or should I just return it to stock and settle for 32-33mph?
Carb is clean, with a new float needle.
Thanks!
