    Thanks everyone for the suggestions. Tearing the head off now, will post pictures of what’s under there.
    Dave running 24:1. The discoloration on the exhaust housing was there when I bought it. Don’t know anything about the motors history. New points,plugs,coil,rebuilt carb etc….Compression is good, starts and idles down well, just that housing is hotter than hell.
    Stay tuned.
