glow plug stuff

[new kid]

yo, what's up rcnt buddies? i got a question. why does my glowplug go black after a 2 hour use? does that mean it's too rich?

That could mean several things.

A good place to start is, is the plug in there nice and tight? Is it a long plug, causing the piston to come in contact with it at top dead center? Is it just the filament that is black or is it the entire bottom of the plug- you know, all caked with grime and crap? A little more information would help us deduce your problems.

it is a small plug, for my kyosho inferno gt. it's just black and oily. i dont put it in too tight but tight enough for it not to come out.

Could be that you're too lean by a hair. Just lean enough to bake the oil, but not outright burn it off.

Black and oily usually means too rich or the wrong heat range for your fuel.
