1980 yamaha gt 80 fouling plugs #1
Im trying to get a 1980 gt 80 going for my grandson, we have went thru the carb, points, cleaned out the exhaust, everything i can find on line that might cause the problem. plug is always black and wet and seems oily. trying a little hotter plug. I thought I would try mixing my own gas see if it makes a difference. Disconnected the auto lube. My manual says the premix is 15:1 can that be right?? I tried it at 20:1 and seems to be better but it smokes quit a bit. Any help is much appreciated
