Okay, new thermostat still no worky. Pulled the fuel line, its clear, left it disconnected where it goes in, kinda pointed out to the side and fired up the machine. Hit the trigger and no fuel(I did this recently after I changed the filter and had good flow). I'm thinking it might be the flow switch??? There is a little bleeder screw on the side that I loosened while it was running and it started squirting diesel so I don't think its the fuel pump.
I understand its blowing but if it is going bad there will be a dead spot in it that when it stalls just enough to let the air fuel mixture get off the flame will go out.Mine would work sometime an then it would load up with fuel and light an it looked a smoke stack.If you havent had it tuned up in the last little bit those electrode thingys could be off as well.Good Luck with it.
