Default Tuning my TRX 2.5

Hey friends. I have a 4Tec with a TRX 2.5 power source, but Im having troubles getting it tuned in.

The engine has a big bear cooling head and an os 10 carb. If you can help please do so. I am dying to get some good runs in on this car.

It's tough to give you any advise because you have changed carbs. The 2.5 is a very touchy engine. the best advise I can give you it start rich on the high and low end. and tune But go 1 hr increments. take your time.
