If the LS needle is too rich, the glow plug brand won't matter. The over rich mixture will cool the plug and the engine will quit. Set HS needle at full peak and leave it there, then procede to lean the LS needle 1/8th turn at a time. As the idle improves keep chasing the throttle to lower and lower settings. It best to do this on a test stand so you don't shake your plane to death..
What size is the prop, it sounds too small? Thanks
