bad coil ground?? missing badly after moving coil

Then next question is - have you checked your engine-to-body ground? Post #2 suggested a fix that worked not because he grounded the coil case, but because he fixed a bad body ground (I suspect). Check the voltage drop on the ground side of the ignition module - right back to the neg. post of the battery.

Remember that when the coil fires, the engine block is the positive side of the circuit. Electrode tip of the plug is negative (that is part of the reason that the tip erodes). A solid ground between battery, engine, and body is vital.

I assume you have checked the other items people have suggested (manifold gasket leaks etc.?)

Actually, the body ground was the second thing cleaned. It was fine as I figured, cause I use high copper never sieze on most connections. stuff works good. And I tried to fire it with each componet cleaned/replaced. Witch made me believe the coil needed grounded. But I`m no pro mechanic. I learn a lot the hard way8) To the OP, Did you buy an Intake that was possibly milled for correction on its previous engine? Is their any gap, front view, where the ports attach to heads? Its gonna be hard to tell until you get it running long enough to spray around the sealing areas. Make sure your carb is doing what it is supposed to do also. Float level, not stuck open etc. choke adj. hope its not a DP?
