rzn jeff

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.
