Well the good part is that in a few weeks you'll have Winter and will have plenty of time to work on it.
But you might have a wiring problem that acts up when the engine starts,,,,,did you clip a jumper wire on the Pos side of the coil and run it on 12 volts? Did you turn the distributor when it was running to get it to run better? It could of jumped Cam timing,,,,those plastic gears break all the time,,,,,you might want to pull the Valve Cover or see if you can see the #1 cyl rocker arms and turn the engine over by hand and watch to see when both rockers are up,,,,,that puts the Cam on TDC, then see if the mark on
the Balancer lines up to around TDC. You could also pull the front side cover and watch until you get the 1st 2 lifters all the way up, then check and see if the balancer mark is around TDC. Whats the DWELL when its running?????
