Dang it, my internet craped out after i typed a lot... Well it sounds like a to lean, if you were to rich you would notice a lot of unburnt fuel coming out of the pipe, also you go through glow plugs quite fast sometimes so u might want to go get you some more of them. What do you use to heat up the glow plug? just play around with the idle screw, They are really easy to tune once u get them to an idle. And make sure you break them in properly, a lot of people say different things but i run about 3 tanks of low to short bursts of mid rpms and 2 tanks of mid rpm running around then i just take it easy on it and don't wide open it until i have got through atleast 8 tanks total,But hey i have seen them not broke in properly and they run just fine.... u got me...
