I'm new to HPI. I have the RS4 3 EVO+. I already did the break in, ran about a quart of O'Donnell 20% thru so far. The car sat for about a month without running. Now when i try to run the car, if i take off the glow starter it will stall. I changed the glow plug(R5) and put after run in it after i ran it last, i did remove all the fuel also. It just won't run without the glow starter on it. Anybody? Help??
