just started in nitro r/c. Bought my first nitro car friday. Nitro sport to be exact. I ran the first break in tank and refueled and let it cool down. Adjusted the HSN like the manual said to do for break in and have had nothing but trouble since. Ive closed the HSN all the way and backed it off 2 1/2 turbs back to original setting. Still having trouble. The problem im having is its hard to start and the only way ive been able to get.it started is if i hold the trottle open a bit. But when i.let off the throttle it dies out. Ive changed the plug. So i know its not that. Could it be that my throttle trim isnt set right on my remote. Getting very frustrated. Please help me. And even better help if you live anywhere near lafayette louisiana maybe we can meet up and you could help.
