Sounds like your engine is either incorrectly tuned (probobly too rich) or your glow plug isnt working good.

When I first got my evader it did pretty mcuh the same thing, myproblme was with the glow plug and tuning.

First take out the glow plug, plug it into your igniter and see if its glowing bright red (also make sure all the coils are lit up) if its jsut barely glowing then it needs replaced, if some of the coils arent glowing you should ago ahead and replace it.

Now while you've got the plug out, clean off the gasket and the plugs threads good, then use a q-tip (either dry or with some denatured alchohol) and clean out the glow plug threading on the engines cooling head. When you reinstall the plug make sure you get it pretty tight.

If that doesnt fix your problem (or at least help) then your engine probobly just needs tuned.

If all else fails consult the manual
