I am working on a friends rustler that he bought in the mid ninetes. He has an hpi nitro star motor but it had a four stroke plug in it. I got a new plug and got it running but there is four adjustment screws and i was wondering if anyone new what one is for idle adj. If you want a pic just let me know and i will post one


thanks

Pic would help to identify the engine, it's probably a T-15 or 15FE, does it have a purple cooling head, a square natural alloy head or a circular grey head? And is the block black or natural?
