Default RE: 3.3 problems(big surprise)

Well, lets look at some other basics otehr than the needle settings itself. Yes, 6 turns out is TOO rich for TRX3.3. Something else is wrong. Other simple checks are to do the following:

1) Completely replace all fuel lines and the fuel tank. There might be holes and air leaks.
2) Replace the rubber coupler on the header and pipe. It might be ripped and giving teh fuel tank very little pressure, thuse extreme lean running.
3) Do you have the RB Innovations supercharger on it? If so, remove it! RB Innobvations is junk and that is why you are running extremely lean.
4) Dismount the engine, clean it, and inspect for obvious cracks in the block, if teh carb is loose, if the back plate is loose. If anything is loose, tighten it back up to stop air leaks there.
5) Remove the heat sinc and make sure you have teh proper number of head shims in place. If you compression ratio is too high, you could advance your ignition timing too much and worse, make your engine ping (this will DESTROY it).
6) Completely tear down the engine, completely clean and inspect it. Replace anything that is broken, worn, damaged,impropperly marred and scratched, etc.
7) As you begin to rebuild the engine, RTV seal it to eliminate any possible air leaks or future possible air leaks.
8) On the carb itself, take out teh needles, disassemble, carefully clean, and inspect thoroughly. Replace the needle O-rings. If the needle tips are damaged, replace the needle. RTV thr carb when you put it back onto teh block. Most of all, when you tighten the carb back onto teh block, DO NOT oertightern the retaining scre, this will compress teh carb barrel from round to oval,this will creat a air leak.
