rzn jeff Posted May 21, 2004 Report Posted May 21, 2004 17cc dome head, 2/1 pipe, 2/1 carb, use 110 octane gas, mix 32/1 with yamaha rmix, spark plugs look good, runs great, when you first start for the fist time of the day, seems to foul 1 or 2 of the plugs. After you change them it runs fine all day, doesn't matter if rode 5 minutes or all day needs new plugs (b8es). Fuel shut off at night, new needle in seat in carb. Quote
U8RSAND-Az Posted May 21, 2004 Report Posted May 21, 2004 It's probably just running to rich. You should'nt be fouling plugs that often. Quote
dirttrack25 Posted May 21, 2004 Report Posted May 21, 2004 I wouldnt think it would matter because alot of ppl run their gas and oil mix alot richer like 20:1 and dont have trouble fouling plugs but maybe try mixing at 40:1 see if that helps any? i had trouble fouling plugs with yamalube at 32:1 also Quote
