Default Re: cooling system

Sorry if this is a dupe cause I just lost what I typed <G>

Demo ride for son and grandson was not good last nite. Started easily but ran rough at spark lever position at 9 and radiator belched a large amount after maybe 5-600 feet. Then leaked as went worriedly around block and home...

My findings today before and after a 10 minute idle:
Change from several weeks ago; #1 Plug gap still @ .035 but now heavy with what appeared to be carbon, but timing right on per Toms photo with rotor trailing edge just at #1 cap position & TDC. Rotor and point gap not rechecked. Filled radiator to 1/4" over baffle.

Started easily. Maybe imagined it ran not quite so rough at idle. Exhaust leak at #1 position of manifold is on my to-do list.

Radiator was warm to touch everywhere except bottom center.

Made a 20 second sound bite and would upload if I knew how. Clear is the exhaust leak at #1 on manifold but am unsure what aa "A" should sound like.

I would like to get engine running better before embarking on a radiator expense. If necessary right now, I could pull the exhaust manifold and install a new gasket and/or mess with carb idle & GAV again (but hopefully not have to rebuild right now).

Thanks,

As a sidenote, looks like I didn't catch the oil burning before buying and wife kicked me from garage<G>.
