the guy i baught my timing plate from told me to +12 it
i thought maybe that was too much but he said it was ok......it is on a 4mil stock cylinder motor with 18cc domes that run on Q16 VP fuel or 110.
when i first got it,i was suppose to be running aly. but i could not get it to run good on it so i went back to gas but left the timing on +12,is this a safe timing for a 4mil/18ccdome motor on 110 fuel ??
