glow plug problems
 
in the past 2 weeks ive gone through 2 traxxas super duty glow plugs in my jato 3.3. both times the filament had broke, and both times it happened wen it rolled over. i know its not running too lean because the temp is 250. can you guys help me?????

Could be your running too rich, if too much fuel build up gets on the glow coil it will foul sooner, kindof like carbon on a sparkplug.

What kind of glow starter are you using? Maybe it has a short? I cant think of anyting engine related that would cause a plug to break. They are built to handle compression after all.

Im not sure, maybe you should try a glow starter, that way the ez start wont have to work as hard.

I have a glow plug problem too. I have a hobbico aerostar 40 trainer with a .46 OS engine in it. The last few times I flew it I noticed the power was dramatically decreased and it even cut out one time and I had to dead stick land it. When I got to looking at the motor I noticed I could unscrew the glow plug by hand. I tighten down the glow plug with a wrench so it is pretty tight when I take it up, it some how keeps working its way loose when its in the air. Does anyone have a solution to why it does that. Should I just lock tight the glow plug in?

Thanks David G.

Wrong forum but do you have the copper washer installed?

As for the original topic, use a glow igniter not the stock ez-start one. See if that changes anything. If not try changing plugs.
