[QUOTE="Tazza, post: 18454, member: 82"] Black smoke is excessive fuel, white is un-burnt fuel. The engine is backwards in that machine isn't it? as in the injector pump is not facing out? I'm starting to suspect your injectors may be stuck a little, this would cause black smoke as its not being sprayed in a nice mist. I would also do the compression test just to be sure. You should get 400 or more PSI. The glow plug wire trick works because there could be a problem with the relay that operates the glow plugs. It won't hurt anything if you leave it glowing while cranking too, just don't leave it on for too long after its started. [/QUOTE]
