72 Duster Resurrection

Never Never Never Never try to run a car or anything with bad gas in it. It could destroy the engine. what happens is it gums up the intake valves and they stick open when you stop the engine, the next time you start the pistons will hit the valves and unstick them, which is bad enough, but also you will most likely bend a bush rod when it drops out of the socket on the rocker, and additives to the fuel may help the issue, but then you may end up with a bunch of sediment in the carb.

and yes I know this from experience.

Hmm, seems like there are two schools of though on this one.

Multiple earlier posts in this forum are highlighting the /6's ability to handle at least some percent of old varnish and junk in the gas if its diluted with fresh gas. I know that running junk is bad intuitively, of course, but sounds like there is not a consensus about it...

If I wanted to be safe, whats the easiest way to pump out the gas tank? disconnect supply line to carb and let the motor turn over? siphon gas out of tank?
