My 1956 860 usually runs great, but started misfiring a couple of weeks ago, then wouldn't start at all. Battery is fully charged, wiring is good, has new coil, points to 25thou, condenser, rotor, rotor clip, sandblasted plugs, and I have a good 1/4" white/blue spark.
I have overhauled the carb carefully, used choke cleaner and compressed air in all it's passages, and put a new O ring on the throttle shaft to ensure no air leak.
So I have good spark and gas, but it won't fire. Could this be an air leak, a timing issue, compression problem or what? I've worked on my 8N and this 860 for 20 years and have not seen this before.
What have I missed? Or what has happened? Thank you in anticipation.
