I've been "bench racing" this truck of mine for a while now and finally today I got all the parts and pieces I needed to get it running (busted radio). On the stand the engine was running fine, idling a whole tank at a time with the wheels on the ground. Manually moving the servo I could get it and keep it revved, though it was "boggy" getting up to higher RPM, I figured I could just lean out the high end when I got the radio back together. Also, lots of fuel splashed from the exhaust.
Today I fire it up and instantly burn up a glow plug, something this engine has never done. Now, with the fresh glow plug (and a longer fuel line to accomodate a recommended fuel filter) the engine is more difficult to start and will not idle at all. 90% of the starts I didn't even have time to put down the glow starter and pick up the radio before it died. After several hours of small adjustments to the idle speed screw and the low end needle, I can drive the truck about 10 feet before it dies. It accelerates very slowly, and even at half throttle usually the engine will die before it builds up much rpm. Still a lot of fuel coming from the pipe.
I'm a novice to nitro, but my gut tells me it's getting an inconsistent flow of fuel, judging from the irregular idle sound. I also notice fuel moving back up into the pressure line. I've removed the filter and gone back to the 2" tubing from tank to carb (It's a GT so it's a short link). I also reset the Dynamite to factory settings (low 4.5, high 2.5 no idea about the idle speed needle, can't find factory specs for it).
Summary:
Engine is slow to start occasionally
Engine does not idle well
Car only moves a few feet and engine dies
Fuel in the pressure line
Fuel "sprays" from pipe
I'd appreciate any suggestions before I start adjusting it with a ball-peen hammer... :trout:
