Is it possible that with that custom exhaust that you are not getting enough pressure to the tank somehow? I've had that happen and richening the HS needle didn't have much effect. Keep us posted, thanks,

It looks like it is a lack of muffler pressure is causing the problem. I switched back to the stock muffler for trouble shooting purposes. It cleared up all the issues I was having. I left the needle at the positon I had set it with the scale exhaust. With proper exhaust pressure it wouldn't even run without continuous glow heat. I leaned it out to the pointI had it running at 6000 rpms wot pulled off the muffler pressure and it surged to over 10,000. I guess I will have to switch to a perry pump of something to provide fuel pressure at the needle since the scale system doesn't provide enough pressure. Thank You Everyone for your help. Adam
