1973 JH running well after rebuilding carbs and installing new timing gears and belt, until today. Suddenly misfiring on #4. Strobe light fine on 12 and 3, but intermittent or not at all on 4. Plugs cleaned and checked. Strobe light up and good spark when plug is removed and laying on cam cover. Any ideas would be helpful.
