Hello,

I am new to this forum, and I would like to thank in advance to anyone who helps me out!

I am new to the RC world and i wanted to get into it a lil cheap(i know) and I bought a used HPI Nitro rush EVO from someone on Ebay, it starts good, and its in good quality but I am having some motor issues. As you may or may not know there is a high speed needle, a low speed needle, and the idle RPM needle on this T-15 Engine. Heres the promblem that is happening...I gas it up, prome it, get it started, let it warm up a little bit, and start to play with it, as im going, it will go full throttle a few times, and then it starts to bog down. I will drive it back to me, under medium throttle and examine it, all is wll i give it some gas, and it goes, but I will go full throttle again not too much longer after that and then it will stall out on me[&o], I have made both the low speed and the high speed needles more rich, with little effects( although i dont know how much I should turn it) this is what it has done pretty much every time that I run it. At full speed there is plenty of exhaust, i dont think it's the high speed needle (although I'm not sure) can someone help me out maybe point me in the right direction, I appreciate it.

**Edit** I have changed the glowplug, and have had the engine checked and its putting up about 55 on the guage.


Thank You
