I'm trying to get my 2.5r revo to run, I'm running o-donnell medium/hot glow plugs and 20% sidewinder, I will run for a few minutes and then goes dead so I go to start it and it won't so I check the glow plug and it's SUPER deformed, I have already gone threw three glow plugs in the last 15 minutes[X(] I for sure not running lean there's a thick trail of blue smoke, can running to rich cause this?
