Just installed an airsal kit on my sprint which as an A35. All new gaskets and everything, fairly new 15.15 dellorto, technigas, 68 jet. The carb, and exhaust i've been using for months. I hook everything up, and kick it over, and it runs WOT on me choke or no choke. Is it likely to be an air leak? even with new gaskets? i wrenched everything down pretty good...
