too much smoke and wont lean out

[jacko88]

I have a kyosho inferno mp7.5 sports, and lately I've been using a 10% fuel which was alright, but i tried my friends 5% fuel with castor oil, and it went so well, i got some 10% with castor oil. When i tried it out, there was heaps of smoke everywhere, and when i was staying to one area, it was hard to see the car, and its never been like this before. I thought because of the fuel change, i'd probally have to tune it, so i tested the temperature and the spit stayed on for about 6 secs, so i leaned it out. I ended leaning it out so far i was about half a turn from the most the needle will go, and i dont wanna reck it. The car was also making a weird noise as if it were electric, and there was a line of grey liquid under the air filter, and i would think thats comming from the fly wheel. This may be another problem, but there is fuel bubbling around where the glow plug is too. Please help!

If I were you, I'd reset my needles back to stock settings, buy a new os #8 plug (use new copper washer), and switch to a 20% nitro fuel. These engines aren't designed to run well with anything lower than that. They will run, but like ass.. Retune it and you should have better results...

I'm going to third the notion and say to use 20% nitro. The 10% does not have enough punch for the .21 engines. Check your manual.

Sounds like time for a 'do over'. Have a Coke and do what
ImBroken suggested and take it from there.
