Hello, I have a 1978 Chevy Custom Deluxe 305 2barrel
It was sitting for 4 years.
I bought it, changed fluids, all new fuel system, rebuilt carb.
Seems to run fine.
However I took it out for the first time today.
Smoked like a train, white smoke. Doesn't smell like oil burning.
No water in oil, and antifreeze level stays full.
Sometimes when I start it, it spits out about a half cup of water.
And sometimes I see water under catalytic converter.
Any ideas appreciated.
Can the converter be bad???
