Screw it all the way in, then back it out 16 to 18 clicks. It should be close.

ParticipantScott,
Sounds like you might have an older model knob for your exhaust valve. Get a thumb screw style knob that can be adjusted on track and set it where it feels best for you. The spring rate and bellows (condition / stiffness) seem to have a fairly big affect on where to run this screw.
If you take the power valve apart, make sure you have the stud re threaded properly and the gasket oriented to not block the vacuum port.
Clean your power valve after a track day, keep your battery topped off during the day, keep your starter bendix clear of chain lube, keep your chain lubed, aligned and at the proper tension, change your gear oil every couple days, keep an eye on your exhaust baffle (for breaks) Go out and run the wheels off the thing. It is a reasonably powered, low maintenance package that is great to get experience with.
Glad to see you’re reading the manual. There are a lot of questions answered there but, our altitude can have fairly significant variances in a few area’s
I’ve seen you sniffing around the forum. Good luck and welcome to Colorado Karting. If Roman and I can do anything to help, let us know.
Rick
