nitro 4 tech 3.3 engine problem(please help)
I got my Nitro 4 tech 3.3 today. Everything is fine, except the engine... when i first started it up it would idle. then when i got on the gas(ever so slightly) it died. now it wont even idle. ive adjusted the carb as directed(4 turns counter clockwise from closed). I am not running traxxas fuel. the hobby store was out so i bought blue thunder racing fuel(20%). i am not seeing any smoke come out of the exhaust. there is air coming out, but no smoke. im stumped, please help me out

RE: nitro 4 tech 3.3 engine problem(please help)
Hmmm....you are confused over what exactly?
Let's see if we can help your decision making process: Should you richen it or lean it? Well, since no harm will come from richening it, let's do that for kicks.
If you richen the setting by turning it counterclockwise, absolutely no harm will be done. Hey, for kicks, let's try that first.
Did you try it? What happened? It got better? And you can give it more throttole? Great! Now you know what was wrong!
Or....did it got worse? Oh, well now you can lean it out, and be confident that you were choking the engine with too much fuel because the factory starting points are always very rich (rich=lots of fuel vs air).
[Blue Thunder (BT)will run ok...but the oil am't and type in it can lead to the one-way bearing slipping when starting, but so does Traxxas fuel. BT and Traxxas fuel are probably the two most hated fuels in the RC world. Not everyone has issues, but enough people do to make them notorious pains in the A*s.]
