4y running on two cylinders
Posted: Wed Dec 20, 2023 12:20 pm
So my 4y decided it wants to give me bollie....
Started with some splittering and hesitation and grew to what it is now....
It seems it is running only on cylinder 3 and 4.
I have replaced: distributor cap, leads, plugs, rotor.
I even had a Chinese carb on here before it happened since the float in the original fell apart.
Timing has not been changed, all vacuum pipes are correct.
Took the new plugs out, 3 and 4 are dark black with 1 and 2 still clean.
There is spark for all plugs and strong too.
I am now at wits end.
Took the cover off, rockers are rocking and valves seem to be opening. No noise from lifters or any engine noise.
Any thoughts or suggestions?
