Mine was grounded to the firewall with a grounding washer and it wasn't good enough, even with the firewall/subframe ground strap in place. Grounded to intake manifold with a good engine grounds and erratic problems neutralized.

BUT, the old MSD distributor worked fine at the time the car was shut off the last time it was run. The two distributors use identical electrical connections and they utilize exact same WeatherPak connector - Plug n Play.

When I installed the first distributor I used a firewall ground - FAIL, switched to an engine ground and VAROOM. So I know the ground it good.

I picked up some new carb gaskets to eliminate the the vacuum leak possibility.

The car sat for several months with fuel in the carb? This ethanol junk we spend too much money on, is quick to goo up stuff. I have to run everything I have out of fuel if I'm storing it for very long. Just a thought....

Not picking on you just observations. My MSD wouldn't function with the same ground the previous Mallory Unilite used..........much more sensitive electronics.

It's a slow methodical one step and test process...........

When I pull the carb off for the winter, it gets drained of all fuel. Last weekend I blew out all of the air and fuel passages in the main body and metering blocks, so all should be good there.
