I'm a nitro n00b and the only fuel I have ever used is Traaxas 20%. It worked flawlessly for me - lots of power and easy to tone.

I think cleaning the carb is part of the maintenance routine - at least for me. From now on, I'll clean out the carb and fuel tank after every 1/2 gallon through.

I also noticed my needles are much more easier to tune after a super clean carb. Note to self- If your engine is struggling to keep a tune, take out the carb and clean it.
