Want to be careful about getting antifreeze in the cooling water pick-up pump softens impellor an can spin on shaft in some. I also think the anti-freeze is good for inside of risers an manifolds.

The suggestion about treating your gas is a great one, try to run it long enough after you do to get the treated gas in the carb.

Then I fog the motor with Marvel Mystery oil and stall it out after a little bit.

I restart with fresh gas down the carb.
