Look down in the gas tank and see if there is a screen inside on top of that sediment bowl. I have seen a screen inside the inlet to the carb where the fuel line attaches also. Be sure they are clean.

Cory..........the friggin' manual ain't no friggin' good fer adjusting the M/S carb. Turn the down-pointing mainjet to 2-turns and LEAVIT!!!

Adjust the side-pointing idlemix for fastest idle, NOT smoothest idle. Understand the difference??? The last time I adjusted my eazy starting 6V-8N, the idlemix was 1/4-turn.

Try these instructions and report back. ........Dell

Cory........NO, it aint'chur friggin' governor. 10-sec run time is usually BAD condenser. Even new condensers can be bad outta the box. ........Dell, sparkie-meister

if it will help,,,since these engines use a updraft type carb,if they dont fire to burn the gas,they can actualy pull so much gas that it Runs back out of carb throat giving every appearance that its flooding. Technicaly it does flood i guess but its not because of the fuel system having a problem.Im with dell on this one,if it will fire,run for a few seconds,then after it cools down do it again,i would suspect the ignition and more than likely the condensor. dont mess with your gov.it simply holds the engine rpms at a constant speed .other than that it has nothing to do with the engine running unless of course it goes wide open and blows it up! most folks automaticaly think fuel problems,but the real truth is if you keep clean fuel in your tank,dont let it gum up,theres simply not a whole lot that can go wrong with a carb.and in fact they will last almost indefinitly.ignition on the other hand has a lot of parts,running at high voltages,etc etc.and one sure fired cinch is youll never fix a ignition problem working on the carb. most assumed fuel problems however are fixed by repairing the ignition!

heres a very simple diognostic trick that may help you out... TURN YOUR FUEL OFF at the sediment bowl! Engine in no way can flood with gas off its simply impossible.After you turn fuel off try starting engine,if it starts after a few cranks you KNOW problem is in carb. If it still doesnt start problem is most likely ignition.Doesnt diagnose running problems,but its a easy way to check start problems.And of course carb bowl has to be full.
