yeah i got my $500 carb and i cant get the bog out of it!(north carolina 300 or 400 ft above sea level,70's temps right now ) if you rev it up then hit it it will go but smack it from a idle and it will cut off and puff black smoke. supposed to be a bolt on five horsepower. i jetted down and nothing happened. i took the air lid off and it was worse. i adjusted the air fuel mixture screw and nothing changed. does anyone now how to set up this carb? my friends got the same carb but from powerall and bolted them on and they worked fine. anyone know how i can reach powerall? sheet with carb says, pilot-50, needle-ocdvr, clip 4th, main-175, fuel/screw-out 2 , main air jet-200, pilot air jet-100 and said to leave air box on with k&n. please help!

 

Were the directions specific to where you live

 

Your $500 carb is junk.

If it's an FCR I'll take it off your hands and give you 0.50 on the dollar .

 

Is it a 39FCR or a 41FCR? Where did you get it? If you are looking for Powroll, their number is [541] 923-1290. If it's Powerall,I don't know.

 

Sounds to me like too much accelerator pump... does this carb have one?
