got a question. I was running my slayer in a little bit of mud. Then it shut off. The mud was really water mud not even deep. So i check it adjusted the needles alittle. Then i ran it in the street for like 3 run bys. Then i stop and looked at the engine and relized that inside of the head where the glow plug is was smoking. So i took it out and saw it was kinda dirty. Look like maybe a little mud spreaded and got alittle slimy. What should i do. Is this something that will eventually burn off. Let me know any ideas.
