If the ignition timing is accurate (and you aren't getting cross fire from
a defective cap or plug wires bundled together), I'd wager either slipped
valve timing (unlikely) or a burned valve seat (more likely). But first,
check the valve clearance to be sure you don't have one that's too tight!

A compression check may be a quick way to spot something.
