My 1972 Nuovo Falcone Military, which I've had running great for 2
months, crapped out on the way to work (leisurely pace!) Saturday.
Sudden loss of power, backfiring through Carb. Won't start, backfire
through carb every time. Checked points and timing, no change. Checked
valve gear--1/4" clearance(!) at exhaust tappet without any change in
adjuster. Compressed air through spark plug hole yields no leak at
exhaust or intake. Pulled header and looked in exhaust port--valve
appears closed and believe I can see the seat(??) which looks
undisturbed, but am suspicious that the seat has migrated into the
combustion chamber. Any way to verify this without a teardown? What
next?? HELP!!!
