Scott's '66 Continuous Modifications.

Which is the correct cam lobe on the distributor shaft for #1? Is that visible under the cap? What is the correct alignment? On the lobe? After?

I’ve always just used TDC then oriented the cap and distributor as in the manual.

 

Ok... soo... here's the deal...
With odd and semi odd motors it is possible to have the distributor rotor 180 out. Not just the crank to distributor like a v8 but the distributor can possible be mixed and matched with rotors or what not to where the 90deg and 135deg interval is reversed.
See your distributor rotor has either a short long shirt or long short long depending on which side of the reluctor or cam the rotor faces. You can always zero number 1 and 3/5 will follow but the 6,4,2 side can be 30deg off just by rotating the rotor 180deg on the shaft.

 

I still don't understand how to check this or fix it....

 

It seems strange to me that your vacuum draw is considerably less on one bank compared to the other.
No matter the ignition issues..... you should be drawing air in equally on each side.
Have you removed the valve covers to verify that the rocker arms are moving and the valves are opening on the cold/less vacuum side?
How long have you run the engine, and what was your oil pressure like?
There should have been a pretty noticeable misfire when you ran the engine.

 

You will want #1 on either opening the points when coming off either the shot duration lobe or the long duration lobe. Pretty sure it is the short lobe as
in 90-150-90-150-90-150. The points open and you get spark. You can see the lobe with the rotor off. You have just 2 tries to get it right. Make sure you
are on the compression stroke at TDC. Not sure if you have the Pertronics or points in this distributor. You got this.

 

Ive only run it for short periods as I didn’t have any coolant hooked up The oil pressure was building to about 30lbs. I did run it with the valve cover off on the cold side. Everything went up and down and all the pushrods spun around.

 

It’s Pertronix. I took the day off from the jeep yesterday. I’m just now home from work so I’ll be out there in a little while to try again.

 

I do understand the concept of what you are saying but I’m not exactly sure how to fix it. I re-clocked the distributor about 30*. I’ll report back shortly.

 

No change. Still hot on passenger side and cold on driver.

 

Move the wires one post clockwise all the way around and re-time it.

 

#1wire went to 6 post
No change.

 

Squirt a little fuel down the throttle body for that side and see if it fires.

 

In your pic it looks like you are stabbed pretty close, within the margin of advance. If you verified you are on 1TDC compression, next thing I'd do is verify spark on 1,3,5. If you have it, move on to a fuel problem ( there's a remote possibility you have an assembly, internals issue but Occam's razor first)

 

I think he verified spark with the timing light, though not the same as visual. That's why I went to fuel. The Pertronics install comes next
if the cylinders don't fire with the fuel. Processes of elimination. Not sure if he ever got the Pertronics working before.

 

If the timing is correct I would be looking at that injector not delivering enough fuel or any at all .I ran into this problem on a 302 with a spread bore once.

 

Mouse bed inside the intake on one side? Not trying to be funny, there could be some sort of obstruction keeping the fuel from reaching the cylinders on one side.Vacuum should be equal on both banks. .

 

I did pull the TBI off the other day to check if I somehow left any rags in the intake.
I did also look to see there was fuel coming from the injector on that side, need to check that more carefully today.

 

Can he Rotate the throttle body around on the intake and see if it stays or follows the throttle body?

Hopefully there isn't a hole in a piston.

 

After messing with the distributor for the past week recently y’all said look at the fuel. Obviously I should have looked at it after the first day of half engine running but I got focused on distributor. This problem was so easy to fix I hate to even post about it.

Start the engine and a quick look down at the butterflies it was easy to see no fuel on one side. Quick YouTube search and it seems I have a somewhat regular problem. The injector comes unplugged easily and stops working. Less than an hour from walking into the garage it’s running on all cylinders.

 

Woohoo, good news!
