Check to make sure the choke is not stuck, and look for obstructions in the airbox or muffler. Good luck![
I HAVE A 79 LYNX WITH THE 275 TWIN FREE AIR. 120LBS. PER CYL. GREAT SPARK BOTH PLUGS, AND ITS ONLY RUNNING ON ONE CYLINDER?, DOES ANY ONE KNOW WHAT ELSE TO LOOK FOR? THANKS FOR ANY INFO!!!!!!!!!!![/b]
When you pull the plug on the non-running side, is it wet?
Also, the side that is not running - is it on the side with the impulse fitting? If so, you could have a bad fuel pump diaphragm causing raw gas to go down the impulse hose into the crankcase and flooding it out.
