Hello,
I just recieved my first Nitro RC from Tower Hobbies, A firestorm 10t. It is the first nitro i have owned but it seems to be having some issues. It took me a while to get the damn thing to start the first time but after that it was running well. I did the break-in according toHPI (idle a tank through then run a few tanks at 1/2 throttle) I had to quit for the day after that and go to work. This morning i tryed to tune it because i know HPI has it set rich for break in (you can put your hand by the exaust and it will get wet with fuel). I leaned it out a bit (about 1/8 of a turn) and lowered the idle. It wouldn't start so i tryed to put it back to factory setting and it started but running full throttle. I shut it down and i tryed lowering the idle but it wouldn't start. And ideas?

Heat the engine up with a heat gun or hair dryer for a couple minutes. It makes starting SOO much easier.

Was it running full throttle, or just with throttle applied? Either way, it sounds like a radio/electrical problem. Take off the air filter and see how far open the hole it in there. It should be about 1-2mm at idle

Yes, it sounds as if the trim on the throttle is set so tight the carb is actually closed. Take off air cleaner and verify the positions of throttle barrel at different throttle settings. (full half quarter) When WFO it should be exactly that WFO! Half is half and so on till you let go off trigger, at this point you'll see throttle slightly open, 1-2mm. Id even be happy with 3-5 mm open. Dont try to make adjustments to ANYTHING without the motor being warmed up. Did you buy a temp checker? If not get one. Warm motor up then make your adjustments. You should NOT have to mess with low speed. Leave it in stock position. (flush) I see more and more people get themselves into trouble trying to tune a motor by messing with low speed. Get all others straightened out before messing with low speed. Again, YOU SHOULD NOT NEED TO. Good luck and if you have any more questions ring us up.

In case you're wondering, WFO means Wide F***** Open (in my dictionary at least). Same as WOT or Wide Open Throttle
