have you tried a consistent flow of starter fluid down the carb while cranking (2 person job) to see if it runs?

if you try that and it runs... you're simply not getting fuel to the engine

this could mean many things....

Run a wire to the + of each coil from the battery, then crank it over. If it doesn't run then we will have to study this one some more.

the coil is geting fire took the top plug wire off it gets spark but the two wires off the dizzy might not be correct , i just hooked u some wires that would go that far i think it might be in the dizzy sence the motor that was in the truck was the douple spark , so im thinking the wires that are there r for the dual spark, so any body have a pic to show the wires to the dizzy and coil would prolly help lol
