Runs at idle but won’t rev

So I recently purchased a Pinz and was running great until I accidentally left the ignition on and fried the coil and pertronix module. Replaced both the coil (flamethrower 3 ohm) and the module and after some time turning over the motor it fired.

Sat and idled fine for a few minutes but when trying to give it gas it wanted to die. I shut it off and just after it had trouble starting again. Everything was running fine up until I fried everything the other week and thought it would return to normal after replacing them.

I’m curious if maybe the ballast went bad too after leaving the ignition on or what it may be. Seems to be getting plenty of fuel. And the spark looked strong when testing it. Would like to know what I may be missing or what else to look for. Thanks

Check to make sure that the centrifugal advance in the distributor
didn't get hung up when you did the replacement.

So two things I found and thanks for the help. Turns out the ballast was already disconnected for the pertronix that was previously installed. I replaced the flamethrower coil with a bosch blue and it fired up and ran perfectly. Thanks
