I made a new gasket and massaged the 2 mating surfaces a little flatter with a flat surface with 400 paper and WD-40.

This improved things but not to where it would run.
I discovered the intake valve was still leaking when I poured alcohol in it.

Went to O'Reilly's Auto Parts and picked up some coarse and fine valve grinding compound.
I believe I lapped the valve in pretty good. The valve guide is sloppy and may cause further issues. (I hope not)

Made a new gasket and assembled it with high tack gasket sealer on both sides of it.
While it won't harden, I am still letting it set up overnight. I'll check the bolts to see if they need a little more torque tomorrow.

At some point I will need to tackle the governor which needs a new center shaft as it is useless as is.
