i think 50:1 was rich so i tried about 70:1 ( after draining the remaining fuel out of the tank ofcourse) i changed around the spark plugs but i dont think they are the greatest, and we got it to start twice. any recommended fuel mixtures for like 2mm overbore with new wieseco piston??? cuz we thought running it a little rich might help but it seems to have backfired so.. what might be a decent ratio??
