after replacing a part on my lawnmower, it seems as if the rpm’s are higher. how do you adjust this?
jose d asked:
i only replaced the intake manifold. does the gap from the coil have anything to do with it? its just a briggs 4 hp motor.

Hello
More then likely while you were fixing the intake manifold you most likely adjusted the throttle without knowing maybe by knocking into it, etc. This would cause a higher fuel flow and increase the idle and rpm rate. It’s also possible that the intake is hooked up incorrectly (no offence) and is taking in more oxygen then it is designed to causing an increased rpm rate. Play around with it a little try to close and widen the gap seeing if one or the other works to decrease the rpm’s at all. If you get no responce try lossening the throttle. Goodluck!

The carb has adjustments on it. It is at the top of the intake tubing. just lower the idle a little bit. PBcompanies.com
