Nimbus, my Q came originally with a 122.5 jet, as I think most do. I changed it to a 125 when I changed the exhaust. Send a PM to forchetto and he should be able to help you with your issue. It's been awhile since we've heard from him any way.


Edit: there is a needle on these type of carbs also and the clip can be moved. Maybe the PO moved the clip to make it run richer.
