It has electronic ignition.
I disconnected and plugged the pcv hose on the carb. Now it is running decent but making no power at all.
I also removed both valve covers again
-Everything is moving up an down
-All the pushrods easily spin
-The pushrods all go into the cup
-The rockers are on the right sides, the cup for the valve is toward the center
-Stock rockers
-Some rockers are marked I63+ while others are marked I62+
-On the passenger side all are I62+ except for the rear most
-On the driver side they alternate between I62+ and I63+ so some I63+'s are on the exhaust while others are on the intake.
Anyway, I think I am over my head now so I may be bringing it to a shop.

Before taking it to a shop ask around and find a shop that understands the old cars and has a good reputation.

Also, a compression check is very easy to do yourself. Remove all sparks plugs, wire carb all the way open, screw gage in spark plug whole, crank starter a few revolutions, look a gage. Write it down for each cylinder and post up the numbers. No need to pay to have that done. Its very easy to do.

The shop I am thinking of bringing it to is run by an about 60 year old guy. He knows old stuff and has an old Rolls in there now. Tomorrow I am going to ride my bike to the parts store and buy a compression tester. Also, I removed plug wires one at a time at idle, when I removed about about 4 of them, not all at once, the engine seemed to labor and want to die until reconnected. But when I removed another 4 it didn't seem to make a difference. Maybe I am running on 4 cyl and that is why it is making so little power. Maybe if I disconnect the ones that don't make a difference all at the same time and it barely makes the rpms drop I could find my problem. I am just speculating right now.

From what I have read on this , it sounds like a carb problem. Reason for backfire could be lean. Engine running the same with 4 wires disconneted is running on half the carb. Try a known good carb.

Wow I just cleaned the spark plugs nearly all of them, except maybe 4, were fouled
Its like I injected steroids into it. The power is mostly back. I am still bringing it to the sop on Monday to make sure though.

Sounds like something in the cylinder heads or rings is causing the plugs to foul. Were the plugs oily? That compression test will tell all. It is more than likely in the head/s, especially if they were just put on.

Was the cam properly broken in and is the proper oil being used with a greater amount of zinc? Maybe a lobe is worn down.

You are on the right track and learning, so hang in there.

In regards to those who are immaturely badmouthing the op, back it down a click or two. This is a harder to find problem for someone learning and sometimes things are hard to figure out, even when explained. If it hurts the motor, it can be replaced, which isnt the ideal solution, but it can be done if it is shot. Remember, this is his car and NO ONE needs to tell him to drive something else. I was once a younger Mopar enthusiast (now 23) and went through similar learning processes when I was in my teens. I have great knowledge now and can fix many Mopar related problems and build motors myself. It took time and I feel good now, but still, no one is going to put down my knowledge or my cars and have it bother me. I simply ignore that arrogance, or combat it with my knowledge. Some individuals need to realize that being rude and unaccomadating is not very neighborly in a great Mopar community such as this. Lets respect each other hear and help out, regardless of the fact that it is sometimes difficult to get the message through to some individuals with issues.

The plugs were oil, while some were almost all oil/carbon, others were oil, carbon, with white on the ground strap.
The motor was "rebuilt" by the last owner about 3000 miles ago I think. I don't trust the previous owner anymore though.
I do not know if the cam was broken in properly but I did take apart the oil filter from 100 miles ago and it seemed fine.

Is it using any oil that you can tell, or is that normal? How many miles to one quart usage of oil?
Seems like a valve issue to me. if you get some compression numbers, PM me or post them. I will try to divulge what you've got. The only other way plugs could be this fouled is not from firing much at all to burn off the oil, but for only the right side plugs to be like this is a bit suspicious.

Both sides had oily ones randomly thrown in. I have only driven this car 100 miles since I have owned it. On startup it burns oil for about 30 seconds, but not much then it goes away. I couldn't get a compression gauge today because of rain.
Edit-Here is a picture of the best plug before cleaning, one had a sludge-like compound on some parts of it. I am running 15w-40 Rotella T with a bottle of STP blue stuff. Now I'm mad I didn't do the compression check while changing the plugs I used 7 different techniques to get all the plugs out and it takes about and hour and a half.

If its burning any oil on startup, something isnt right internally. Bad valve seals fouling the plugs would be my first guess, if not, poorly sealing rings. Is the smoke blue? Could also be a bad set of intake gaskets, but lets get the compression test first.

With a little time, we will get to the bottom of this.

Tomorrow I should hopefully have a gauge and be able to test. I just pulled the number 1 and 2 plugs, since i just did a little WOT run after cleaning and quickly shut it down. The 1 looked fine, just like when I put it in. The 2 was already oily.

Your plugs are probably carboned up like that from being too far advanced with the timing. When I advanced the timing on my GTX from its stock initial location at 6 degrees to 15 you could see the black smoke start to pour out of the pipes. Try putting it to stock for a while and it will probably clean the plugs up pretty good. Pull them after its run for a while and if they look good you should be good to go. It might be hard to burn all of the carbon off though.

1. Please stop running the engine at WOT.
2. Do not free rev (neutral or Park) more than 1800 RPM until you have got it running right.
3. Try to follow advise laid out here and in most older automotive books. Test the basic engine first (Compression), then check ignition (which seems like you have covered), then fuel supply and delivery.
4. Note the intake manifold. If it's a stock dual plane, half the motor is fed by one side of the carb, (2 outers on one side, 2 inners on the other). This can be the reason that half the cylinders aren't firing. See if the pattern matches. If so, determine which side of the carb is questionable. Also check for vacuum leaks that may affect one side. PCV and Brake Booster are common. A small vacuum line usually won't cause this.
5. Understand that the reason people do things in a certain order is through experience and training. It may seem like they are crazy doing harder things first and that you want to check stuff in a different order (no tools or easier). There is a method to the madness.

I am pretty sure that the black stuff on the plugs is oil. The timing is where it should be now. I cleaned the plugs really good and the number 2 is oily again.

I also would try to tune the carb. A lot of times when a plug gets fouled from over fueling it is toasted and will not fire right, even after cleaning. I just went through this with my dakota engine swap. Buy a new set of plugs and try it again. Turn your carb screws out 2 and a half turns and see what it does. I also ride sled in the winter and motorcycle in the summer. When a plug gets fouled it goes straight to the garbage can. When I put the smallblock in the dakota I used an old set of plugs with a new carb and a different distributor. Had the dizzy in 180 off and fouled plugs. Even after getting it fired up I still had to put new plugs in. Just another example of plug problems is a co-worker sold his newer arctic-cat sled for very cheap because the mag side cyl would not run right. good comp and a great spark with the plug out. Plug in ran like crap. Sold it and the new owner put two new plugs in and it ran like a new sled. Old cleaned up plug would not fire under compression. Taught me a lesson also.

That also makes sense to me, but I believe I have the idle mixture set correctly and my primary jets are now the stock 65 size.

The oil might be coming from a bad valve stem seal. You can pull the valve cover and see them through the valve spring near the head. Usually if bad they break into pieces from getting brittle. Below is a pic of the seals. I beleive the short one (umbreller like) is exhaust and the longer one is intake.

Hey there Bordin, please remember that it is very easy to blame a carb for engine problems. Most people think that way, actually. But 9 out of 10 times the carb is suspect, it's actually something else.

You are on the right track. You have a wobbly vacuum gauge reading, which indicates a bad valve, and that is likely. The compression test will verify/deny the suspicion.

Once you have the mechanical aspect of the engine in good shape, THEN you can start blaming ignition and carb for your issues, but the engine must be sound first and foremost.

You're getting there!

I agree. With the oily plugs and the backfiring through the carb, it sounds like either a major intake leak or a bad valve/s. I would almost wonder if the owner knew about this when he sold it to you and just cleaned the plugs before he sold it to you.

Mudslinging aside, you are getting close to a diagnosis.

I was definitely played when I bought the car. He said it had new brakes, rebuilt engine, a new interior with one seat needing recovering. All it had a was a very good interior. The brakes look like they could be original and the engine looks like a "new" set of heads and paint. The owner conveniently can't find the receipts. The car is very solid however.
