Re: Vapor lock percolation?

Don’t trust the regulator. Especially that cheap style. Adjust it down to 3 psi. See if that helps.
You can’t see the transition slots unless you pull the carb off. They’re under the throttle plate.
Leave the spacer in place. Check for vacuum leaks. I use wd40.
Some timing lights don’t work well with an hei.
You can adjust timing by ear or use a vacuum gauge. Listen as you advance it slowly. You’ll hear it smooth out. Or set timing to highest vacuum. Then check with your timing light.
A new carb or new filter doesn’t gaurentee you have a float set wrong or trash in the carb.

Did you have fun putting the metering rods back in when you had the carb apart?
