Ruff Idle ...
Had an 500 traxter with ruff idle...I cleaned carb and replaced gaskets and float value,adjusted fuel level several times still rich idle....after hours of working on this..I turned the fuel value off an bout 3 seconds great idle ..I did notice when rich and ruff idle the carb never was showing any signs of extra fuel.. so after I turn fuel value off for bout 3 second great idle I started thinking how could this be..i NOTICED The fuel pump was vaccumed pulsed so I put an clear line on the vuccum pulsed nipple an bingo seen fuel getting pumped into intake to cause the rich and ruff Idle..Replaced fuel pump an runs great Im just sharing this to save some others some time on an rich and ruff idle after you have gone thru the carb time n time again...may want to do to this test on pulse to pump to see if pump okay.:nod:
