EDIT: FIXED THE PROBLEM: Since my glowplug popped out I ordered two new ones, threw it in today and no gas leaking at all woo, but now I have another problem - Going to make another thread on it.


Hello all and welcome to my next problem, I have yet to even drive my nitro car around yet. :(

I have fixed my carb issue in the later threads (yet the car still revs and wheels spin, still trying to adjust needles.)

It seems when I start the car the glowplug becomes lose and starts spitting up gas from underneath it. Never seen this problem before, maybe I messed up the threading or something? (I have taken my glowplug in and out many times already.) My glowplug is in snug and secure so I'm not sure how it gets loose when I fire it up. Any ideas?

Does your Glow Plug have the small copper washer inbetween the Heat Sink and Plug? I accidentally forgot to put one on once and I has an issue of fuel spitting out from around the threads on my T-Maxx..

Yes the washer is still there, yet I'm not sure why it still spits out?
 
i get the same problem with one of my engines I'm sure I've stripped some of the threads in the engine top plate where the glow plug screws into (newbie talk)

Probably because you have cross threaded it. When you screw in the glow plug, it should be very smooth, no resistance what so ever, until you get to tightening it. If you feel eny resistance, STOP IMMEDIATELY! This is a good way to ruin your plug. Also check the gasket for any cracks that may cause a leak. Otherwise, it may be a problem with the thread on the top of the combustion chamber. Which will need to be replaced. It may not even be a leak, it may just be excess oil coming from the heatsink. Wherever you have combustion and moving parts, your gonna have grease deposits, thats just the way it is!
