Hi Guys,

Good news! I finally recieved my HPI Nitro MT back from the Hobbyshop with a New Pullstart installed and tuned.. BUT....

I still need help

I have now been able to start the car *Yay-New-Break-Through* but Im not exactly sure how the car is mean't to act when started. Let me explain...

1) I have noticed that I when I start my car and attempt to accelerate that the engine makes a *deep muffled noise* and the wheels don't spin. If I then turn the tuner on the engine to allow less air and more fuel then the car's wheel's will begin to spin automatically and the car begin's to rev quiet high. *** But Im scared that if I put the car on the ground, it will take off. So I alway's cut the engine cause Im scared it's ganna blow

1A) Any suggestions or TIPS? Am I being to careful or am I doing something wrong?

2) When it's started the engine is not to noisey.. I mean it isn't exactly quiet, but it's not "LOUD" - By closing the engine tuner the car starts to rev a lot higher and becomes much more noisey - is this how it should be?

Any help would be very much appreciated

Thanks in advance.
