Possibly bad rings or weak igition going to the black plugs. Bad wires ect...With carbs may be diffeent..I don't deal w/ carbs
On my CIS I could pull two plug wires right out of the cap while running and the car would not change tune..New wires fixed the problem. Plugs were black on those cylinders. |
