I’ve done a compression test all four are even around 115.
Tested primary and secondary coils per OHM readings, all very similar in spec.
Changed fuel pump diaphragms, cleaned carbs and reset to specs, new spark plugs.
Engine starts, idles and has a miss. It’ll run WOT but it’ll stumble and cut off at idle, even advanced on the Idle adjustment rheostat.
When I disconnect TPS, engine revs up.
I know it isn’t smart but I pulled the plug wires as it’s idling and the top cylinder doesn’t make the engine stumble but the other three do. Top plug is black (although brand new) and the others are clean but definitely getting fuel/oil.
Any help to what I should look for under the flywheel? Sheared key?
