have you tried cleaning the "flapper" area and the inner nating surface? they are also adjustable, yours may not be correctly adjusted, i believe the correct value is .002in maybe wrong, but that value comes to mind. if the flapper is not phsically binding i have seen the fuel accumulator cause similar issues.

hey thnks not for sure wht that flapper does but I guess it is important do I just wipe it down or do I clean it with something special. Guess I prob. should take it too a merc. mech... I live in Purcell OK. if you know of anyone in this area please let me know.
