Help quick!!

I just got a Nitro Sport from a friend. The settings on the carberator are messed up and I need to know how far to unsrew those two screws. The big one and the small one. Please explain in detail, im new to this

[Nitrooster]

The big screw on the back needs to be turned 2 1/4 turns from being all the way closed (turn it clockwise tell it won't go no more do not over tighten and turn counter clockwise 2 1/4 turns).
The little screw beneath where the air filter is, is for the idle. Pull the air filter off and the opening where the air gets sucked in should be approximately 1-2 mm open.

I believe I have all this memorized right if not somebody please double check.
Thanks

the idle should be turned 1 3/4 from closed 1 1/2 for high altitude. im pretty sure

I always thought that too but I couldn't even get mine to start with that setting. I had to turn mine out like 3 1/2 turns before it would even start. Go figure?

Sounds like you have the trx-15 pro if you have both a low and high idle screw. The sport engine has only the high idle screw. Make sure you know what carb. you have, because the stock settings are about 1 turn different, and will make it hard to dial in.

i know they must have messed up in shipping because the engine keeps going dead when i gas it.

[nitroguy]

Did you let the engine warm up before you gave it gas???
