JohnBuckner, Yes I'm military but all the guys I used to fly with are either deployed or have PCSed. I have tuned 5 or so airplane engines and I used to race 1/10 scale stadium trucks. I know how to tune for the most part, not saying I'm a master or anything but I can usually tune and engine by sound alone. My last resort will be taking to the LHS. However, I'm a crew chief so I don't give up easily.

Hossfly, The Stinger is band new, I just finished the build on friday. I always take extra time to look the tank over and lines before calling it good. I had an issue with a split line once way back on my trainer and I haven't over looked a fuel line or tank issue since lol. I can assure you that they are good. As far as pressure in the tank, that's what I'm curious about. I read a post on rcgroups that when using the Bison Pitts muffler like I am most guys had to pinch off one of the exhaust pipes to get enuf pressure in the tank. I really don't want to do this but I will if nothing else works.

jetmech05, I did run 2 full tanks and about 2/3 of a 3rd tank before trying to tune and fly. I know that things will change as it loosens so I wasn't looking for stellar performance. I just wanted it to run and idle like any engine should.
