Yes.
Okay this is going to be difficult.
I presume when you say the
PCV is missing, that it has been blocked off or has been connect up to the crankcase, and not leaning out the fuel mixture?
The
PCV is there to prevent backfiring from igniting the gas/fumes inside the crankcase.
You are going to need to check everything and not presume anything.
It could still be a carburetor induced flat spot, but my gut feeling is it is timing.
You will need to go back and put the no 1 cylinder on TDC after it's compression stroke.
The correct way to do this involves removing the rocker cover. Then turn the engine over clockwise by hand until the valve rockers on the number 6 cylinder are on the rock. On the rock means that the exhaust valve rocker is just closing and the inlet valve rocker is just opening. Then check and make sure that the harmonic balancer timing mark is lined up with TDC. If the timing mark is within a couple of degrees, rotate the engine until the timing marks are lined up. It is now on Number 1 compression stroke at TDC.
If your harmonic balancer timing marks are out by too much it will mean the harmonic balancer has slipped on it's rubber. For an engine this old it is a high probability.It is also where many a mechanic have come undone, they have presumed the timing marks where correct.
Now go to your
distributor and with the cap off, see if the rotor lines up with the number one spark plug lead.
If the rotor lines up correctly, continue, if not get back to me with your results so far.
Now disconnect the coil lead from the
distributor cap and earth it to the engine block such that there is a small gap between the lead and the engine block, You will need to see it when it sparks.
Back off the retaining bolt that holds down the clamp holding the
distributor housing. You will need it loose enough to be able to rotate the
distributor by hand.
Turn the ignition key to the run position, don't crank the engine.
Now rotate the
distributor left and/or right, make sure you can make the coil lead spark.
If you get a spark, rotate the
distributor housing as far as you can in the direction of rotation of the rotor.
Now rotate the
distributor housing in the opposite direction to rotor rotation until there is a spark at the coil lead.
Clamp down the
distributor housing at the point where you get the spark.
The rotor should be pointing to the number one spark plug lead position in the
distributor cap. If not then something is wrong and may require the
distributor to come out and be repositioned.
Your engine should now be statically timed.
Put the engine back together, fit timing light, start engine and reset timing to the desired 4 Degrees advance as specified.
Get back to me with how you went.
It maybe simpler in the above operation to remove all the spark plugs to make the engine easier to turn by hand, it's up to you.
Don't turn the engine over by hand with the ignition switch in the on position, it may start, and it may result in blood loss.
The engine may have been at the 14 degrees BTDC, because the previous owner could not time the engine correctly.
