Okay, got some carb cleaner, cleaned it out, replaced plugs, wires,
distrib cap, and air filter. Oil/Oil Filter and clutch recently
replaced. It seems to do it LESS, but it still does it. Might be
carb, might be fuel filter, and I dunno where the float valve would
be, how do I go about checking the carb further and the float valve,
I'll get the fuel filter changed soon.
