Thanks Mike

Make sure your fuel is not contaminated with water/dirt.  Drain the fuel tank into a clear glass container to see how it looks.   Check to make sure your fuel line isn't blocked.  If you have gas getting to the carb and the problem still exists, pull the carb off to inspect and clean as required.  The problem seems to be "fuelus interruptus" probably occurring at the carb.   

the gas is clean and dirt free.
the primer bulb is to push air into the carb bowl. when looking a the filter housing the opening  of the air passage leads directly into the middle of the housing behind the air filter. and goes nowhere else. can you explain how that air pressure from bulb gets into the fuel bowl of the carbuerator
i'm confused. or am i just going crazy

thanks mike
