Right on Matt. I always try and help customers and others with tuning etc when I can, but sometimes you just canīt fit it all in without it being detrimental to your own racing.

Hmm, I holding off on the GXII inferno. I wasn't meaning you had adjusted the idle yourself, but looking at the low speed needle in the pics, there is no way that puppy would sit there idling with the LSN screwed out like that without the idle gap being a little too wide. Maybe it came from the factory like that ? Every motor I have ever run-in needed the idle gap cranked up some for the first few tanks to keep them running - which is cool when you are running rich during the run-in period, but when it comes time for race tune, that idle gap needs to be knocked right back. With the longer needle carbs (or standard needle carbs for that matter), the relationship between the idle gap and the low speed needle setting is critical and must always be balanced out when making adjustments to either.
I am sure when you do the pinch test you will find it chirps up to pretty high revs, requiring a tweak or two on the idle screw to set things right.
