I just built a serval, and it's doing the exact same thing. I have tried everything known to man to get it to straighten out including taring it down to examine for air leaks. No luck. I run vf3 reeds 35 pwks with pilot at 48, main at 148, and cel needle in the middle. Per Trinity( I know I know) I have tried different combos and it just loads up. I am at 6500 feet, but run almost exclussively at Glamis. I have tried timing, different fuels, I am at my wits end any help would be appreciated. Trinity says air leak, but it has been leak down tested 3 times and never fails.
