Dead engine revival techniques

[Bill K]

I did the Pertronix, coil and wires. In vacuum leak/carb issue/engine issue denial...

[Barry Wolk]

Curious, have you opened up your choke housing? Is there black soot in there?

[Bill K]

Yes, and yes, fair amount of soot.... probably rusted out tube that goes through intake... above my pay grade

[Barry Wolk]

That's why it's running poorly. There's a passage or a piston in the carb that doesn't like carbon.

[Bill K]

Any way to easily bypass or block this off to test the theory?

[Barry Wolk]

Take one vertical tube out and start it up. Exhaust will come out the port. That's the only way carbon or soot can get there. It's not a theory.
