RE: HPI Nitro Rush Promblems
Just for future reference, if your car is bogging down like that (as in it sounds like there is too much fuel for the engine and not enough air to properly burn) then your needle(s) are too rich. However, if this happens and it sounds like there isn't enough fuel and it isn't gurgling at all, then it is too lean. I have the T-15 engine and it is pretty easy to tune. Just get it to the point where it doesn't cut out at all, but keep it on the rich side if you're just bashing so that your engine lasts longer. If you want to keep it, that is.
Sorry if there are some grammatical errors or spelling errors, but I'm extremely tired right now and I'm not really paying attention to anything. So, please excuse any errors I might have made.
Good luck with the engine, and have a good time! Also, if you still have that ridiculously stupid stock air filter, change it! That thing is worthless. Get a MotorSaver filter, and you'll see a huge performance increase. You can't beat the performance increase with the money you spend on it.
