As mentioned previous, did a valve adjust last weekend. Idle was too high, so at noon today I adjusted F/A mixture and set the idle to 1400. First stop light I came to choked/died. Pulled it over to see if it would start. Nada! Pushed it home and opened it up and first thing I noticed was no fuel in the line. Took off gas cap and still no flow so cranked on it and no movement. Disconnected fuel filter on carb side obviously had fuel flow there. Nothing between the vacuum valve and carb. Assume bypass of valve with an on/off valve first?  |

I'd recommend adjusting idle using your idle screw before going to the F/A mixture. If the idle is simply high, F/A is an artificial fix which can throw things off. This could be the direct cause of it not starting (leaning it out will bring RPM's up.. once the enricher cuts out (when it warms up) it will go REALLY lean, causing non-start issues.)

To verify that its your Petcock or Fuel pump whichever you have, disconnect the Vacuum hose from the "T" or "Y" going to the Vacuum Line on your Petcock or Fuel pump and suck on it.
If Fuel THEN flows then you lack Vacuum from the Intake, if still no fuel flow then you have a bad Petcock or Fuel pump.
To get it back in a starting position if you have Fuel flow to the carb, turn the Fuel Ratio screw clockwise until it stops then turn it Counter Clockwise 2 1/2 turns that should be enough for the motor to start and stay running if everything else is working.
