Thanks a lot for the reply. No, I don't have a temp gun. I am on the budget kind of, so all necessary gear I was planning to buy within next few weeks. I tried to adjust HSN and idle but no luck there. I'll try your suggestions and see how it goes but if nothing you suggested works do you think I should contact Red Cat support and try to exchange the engine? This is just my luck... lol... most of the time if I buy/get something new there is always something wrong. I would hope just once things will go smoothly. Since I am a newbie I would like to know from somebody's personal experience, is there a big difference between 1 speed and 2 speed nitro car/truck? I would like to know as much as possible about R/C. I am not planning on racing on the track or something, at least not until I learn how to handle R/C nitro better.
speaking in general terms, 1 speed is more durable and thus better for bashing while 2 speed allows for faster accelleration without sacraficing top speed.
things to try
test your glow plug. put it in the warmer and if you see the coil glow red then it should be good to use.
see if fuel comes out the muffler. generally this means running rich, but it will also mean in your case that the motor has suction and is pulling fuel trhw it.
And if its pulling fuel and not starting, then its more likely a bad needle setting/glow plug or something along those lines.
I assume when you try to start the motor that you have the radio/truck turned on and the throttle setting at idle? (only ask cuase i have tried to start one with radio off and throttle was at 50% and it would not start that way)
also, what fuel are you using? brand and nitro content?
