hi guys my 21 engine low end wonts to be really rich to run with no hesatatshion is this a problem should it be lean

If it runs with no hesitation the way you have it, i doubt its very rich otherwise it would act although it is very rich..............would it not:)??

If not then what fuel are you using??

Hey BTW what low end needle do you turn the gold one one the side? right away from the servo link. my top end sounds great but my low end some times has some hesitation so I'm just trying to figure it out.

It may be scrwed all the way out but would think that it is fine if there is no hesitation. If it was too rich it would more than likely cut out and flood as far a im aware.
Im not realy sure what to think as it seems very strange. I can see why you posted here. Ill searh around and try and find anything that could help.
