Just was curious about modding i wouldnt use this engine for that, id use some cheapo throw away engine, looking at the engine design though, gasoline wouldnt be good.

Anyhoo! Got my engine in, now im looking to get all the recommended stuff for it. However it says recommended break in fuel is Hobby People 15% 2-stroke Sport fuel for break in and normal use. I cannot find it on their website, found everything else and Traxxas fuels. Any recommendations on a high quality 15% nitro 18% synth/castor blend?(required by the manual) Im picky about using top fuel for everything.

Also, when installing the muffler, and i was tightening the lugs, this grey graphite like stuff came out from the mating surfaces, is this bad? I dont think i over tightened it, didnt feel like i was.
