Cannot claim success yet.

Same hard start this morning but got her started, warmed up, pulled and plugged the vacuum line from the distributor, timed her to 9* following all of the rules.

Hard start still so I tuned my carburetor now that the timing was set. I am running a Weber 38, and she sounded great while running. (Based on my experiences today, I think that I am ruling the carburetor out. Please let me know if you think it is related.)

Shut everything down, same result.

I pulled the distributor and put it in at TDC on the compression stroke again instead of the 9*. Same results, left it that way. I am running an MSD 8516 distributor with manifold vacuum.

Right now, I can get her to start easily and run great but she is not timed according to the rules.

When I set the timing at 9* BTDC with the vacuum disconnected and plugged, she will not restart when the vacuum is reconnected.

What I have done by rotating the distributor until I get easy starts and smooth running has resulted in my timing at about 8* with the vacuum connected.

When I pull the vacuum, I am reading about TDC or just after which is about a 9* decrease.

Three questions:

- What should my timing read with the vacuum connected?

- Could the oil that got into the distributor have damaged the vacuum advance assembly? This is my
leading theory. (My instinct is that the amount of drop that I get when I disconnect my vacuum may
help me troubleshoot.)

- Could I have installed the new timing chain incorrectly that would explain this?

I just got home with a fresh set of plugs so I am going to put them in and take a shower. Took a whooping all day with this.

Thank you everyone, I am lost in the sauce big time here.

Thank you,

Michael

Did some homework and realized that I may be in a different situation when it comes to setting timing, I have done a nutter-bypass and it may impact my timing.

I apologize that I did not include this as I did not know that it was important. Lesson learned.

Please let me know if I am correct and how to set timing after a nutter-bypass.

Thank you,

Michael

If you correctly "nuttered"

Your rig should be set up like a 1979 (had no computer--uses the Motorcraft ignition system)

Computer now does nothing and should not affect the timing

Soooo we got 'er to TDC, zero at timing marks and installed the 'stributor????

I also found that I should not have my PCV T-off into the base of the Weber 38 and should go right to the canister instead.

Thoughts?

That's it, I have to go to bed. Thanks again everyone.

Thank you,

Michael

Last thought:

The breather on the back of the valve cover that goes into the air cleaner is open.

Should that be plugged?

Thank you,

Michael

JEEPFELLER,

Yes, back to TDC, zero it timing marks.

I wasn't disregarding the advice, I tried something else because of the advice in the video and from MSD.

Still the same troubles.

What should my timing read at idle, around 700 RPM, with the vacuum attached?

Help me please, I am not learning anymore, just swimming in circles.

Thank you big time.

Thank you,

Michael

Hello,

Got some help from JEEPFELLER and she is running again.

All signs point to the carburetor at this point so I am going to close out this thread and start a new one if I need some help with that.

The only explanation that I have is that when I shut her down after discovering the oil overfill, I was right in the middle of tuning the carburetor and went for the distributor first as the culprit instead of the carburetor.

Thank you,

Michael

I think you need to start out with the basics.

Maybe a 1/6 scale Willys Platform?

Start by not letting the female chew up your gasket.
