I learn something new everyday. Moved the blade just a bit, put it in, works fine. That tb is very sensitive, if the blade touches any part of the housing it won't work. So I ported the 90mm that came on the tbss last night also, installed, works great. Feels like I installed a supercharger now:LOL: what am I gonna do with all this extra power? Thanks for you help. If anyone needs a ported tb let me know, I'll do it for 10 US dollars.
