That's hard to say. Where do you think it need's adjustment ..? Idle,midrange or top end. If it's idling rough,check plug's for wear and color.Color say's alot right there.Check for good spark,plug wire's,coil output,clogged fuel filter,bad gas,air filter. Check for vacuum leak's with WD40. May be time to clean them.
