Timing problem

So far I can't keep it running. If it jumped teeth it just did it as soon as I shut the car down.

This is the gas that was in it. In the filter it was a brown color.
I siphoned it out but today I'm dropping the tank and cleaning it. I found some gel in the bottom of that container.
The car did run on this gas several times. Before I messed with the timing it would fire right up and idle fine. I cleaned the plugs off already.

The cam is stock 1976 cam.

What was changed.
The throttle cable bracket.......had to undo those two bolts back at the intake. Didn't replace the gasket

A carb adapter had to be used to space the carburetor higher for an air cleaner. The streetmaster intake is low profile.
The car ran after all these changes were made. It ran with 11" vacuum.

Once I messed with the distributor. Car wouldn't run at all.
I've always had problems tuning these cars. Vacuum can drop from several places. Carb adjustment.....timing.....actual leak. Never can determine which is which.
I'll be honest. When it comes to diagnosing carbureted cars. I'm terrible at it. Partially because It's old stuff that's worn out and I don't know the difference.

When you have this problem and the car doesn't run you can't find the leak.

When I saw the 11" vacuum. I thought the timing was off with the new carburetor......used carburetor actually. So I went there to find it thinking a regime wouldn't be a problem at all.

What I'll do......
I'll get good gas in it........unhook and lug off vacuum lines to anything unnecessary like thenpower booster to sort out any leaks.
set the timing to 0° again and see what happens.
