make sure your glow starter is STRONG, also try replacing the glow plug if it does not glow very well. then try to lean the air/fuel mix a tad. what is your needle valves currently set at?

what is everyone else running theres at? i know this may vary, post number of tanks along to give a good idea of settings he should try.

i am at 1 1/8 for high speed and default for low speed on 9 tanks of fuel
