Well i just looked at mine, the injector bungs are a very poor design, and i think you would need to replace them, since the top gets stripped easy. I think the only way would be to weld them in and make a different set up, duttweiler does this i heard. I could not get a stable idle, it surged from 600-1600 rpm, and the a/f was going from 9.5-15, surging and stalling. When you have a large camshaft the long runners inside create pressure waves or harmonics, disruptiing the airflow. This is the only thing i can think of why this wouldn't run. However, i was thinking of cutting up the runners and trying it again, to make a like a empty box. But if someone wants to tinker for a few weeks or months they can ship it to duttweiller and maybe he can fix them. I'll sell it for $500 usd shipping included, dust comes free.
thanks
