Customer >comes back and it was "$300 please!" Oh now,,, that's just,,, no comment! I have also seen guys rev the engine up and place their hand over the carb to pull gas backwards through the carb. That would have cured the immediate problem (dirt) but would not have improved the drivability unless the floats were adjusted too. Just for the fun of it I took one that we could NOT cure and richened up the main primary barrel to a normal number. MAN did that thing GO!! $300 eh??? Boy were we too cheap at $150!!! Bruce Hevner
