I tried turning the air screw in but when I reved the RPM seemed to stay up there and take a while to come down. Is this normal? I did this when stationary and backed them back out bc I didn't want to have it like that on the road....
Sorry, I should have been using the "quote" feature sooner since we have several 550's in question here. My head's spinning a little
Anyway, that's not normal. (I assume you know about the knob to control idle speed.) That symptom can be caused by several problems.
If some of your idle jets are clogged and you are idling off the main circuit, that can happen.
Or if the idle mixture is way off, you may end up idling on the main circuit which can cause this.
Any significant vacuum leak will definitely cause this. That means check every vacuum hose for a leak or look for cracks in the rubber intake manifolds.
This can also happen if you are usinmg the choke. That is actually the normal way for the choke to operate on the TK22 carbs you have. That's the only real weak spot on the carbs.
It can also simply be a sticky throttle or cable.
