RE: Shockwave turns off on full throttle
sounds like you may need to adjust the high-speed needle. it may be rich, or may be lean.
is it easy to restart when it dies?
If the motor idles well, and has good low-end power then the idle gap and low speed needle are set pretty good.
It can also be a bad glow plug. sometimes they will still light up when you test them, but not give enough heat to run 100%
but 1st try tuning the high speed. make small adjustments, and remember where you started.
after you make an adjustment, do 2 or 3 high speed passes.
also, when you hit full throttle...just before the motor dies...is there a good trail of smoke coming from the exhaust? If not, then the motor is lean and you need to richen up the high speed(turn counter-clockwise)
