I picked up some gasket material today and some Hb weld steel stick, made two gaskets for the choke thermostat cap. I checked the cap itself for cracks and leaks which it had none. I stacked double gaskets and mounted then I was getting 5 inches of vacuum at the hose to the carburetor horn. I also found out the horn fitting tube was blocked by some yellow corrosion so it appears now the choke tube to the choke thermostat is getting nice and hot now.

Now I just need to install the 1969 alternator bracket and jb weld the splits and cracks in my aircleaner housing.

Thanks for the help wouldn't have narrowed it down without it.
