fuel regulator? Are you running hoses and not tubing? could be colapsing the hose, no fuel then. But if you had E-85 in it. Rebuild the carb and clean it out. Mine would not idle, revved fine, idle = crap. rebuilt carb = charm. E-85 is kind of nasty stuff. you will see a gray/black/silver sediment in the bowls of the carb. If it doesn't work can get my back?

KeithVern, I would check to make sure you have good 12+ volts to the MSD box and a good ground. Also check the resistance at the pick up coil and check the reluctor gap. Probably something simple,if it were valvesprings,I would think it would rev okay and pop and bang at high rpm. Keith

The one set of springs I had did pop or miss... it was just super lazy ... it was in valve float on the whole run.... it was just a suggestion... but you changed out most everything

Sounds like someone put a two barrel carb and a set of mufflers on it. 3 carbs-2 MSD boxs-2 fuel pumps-3 sets of plugs-cap&rotor. all been change. check valve lash 5 times ! springs look ok not that old-Just took the front of the motor apart everything on the timing chain looks great. also change it from e-85 to gas no change. timing is rock solid. 18-34 . nothing in the oil filter. compression test good 100-170 . will not rev up..not crisp and clean. What else to check- ideas..split them out !
What? 100psi is barely enough to fire a cylinder..

I sure didnt see that 100... in my mind it was 160-170 but your right... 100 will barely light the cyl
