318 Engine stumble

The distributor is a skip white Hei.

If you look at the reluctor wheel. It’s not pointing at the matching spike. It’s offset.

I have to move the distributor back in timing advance to get it to line up correctly to 0° at TDC......This is making it retarded.

It looks like the weight system is preventing it from moving to 0°.....butnreally it’s the reluctor wheel in the wrong place. ......I’m pretty sure

If you look at the red circles...its the center piece touching the weights that are preventing it from moving to zero....but this is where they belong.

In the picture ....this is sitting at TDC on the timing mark on the harmonic balancer.
I made sure I was on the compression stroke just to be sure it’s in right.
Should the reluctor wheel be pointing at one of the spikes instead of offset?

I do have a moroso 72300 spring kit on hand to tune the curve. It has a center piece, weights, and springs.........i don’t know what that would do if installed.

Maybe it’s the part of the inexpensive distributor or is it me.



Also....reading some of his post is interesting he instructs is to create the problem I have by fixing his own problem of hard starting.
“GM” Style HEI - Aftermarket Weights and Centerplates - Team Camaro Tech

At the end of this guys first post. He has the same or similar distributor.
He says his advance weight center piece was turned upside down making his car hard to start. He then turned it to the correct way.
.......my distributor came the correct way. My center piece that activate the advance weights is correct.

However.......when he did set his correctly. He gave instructions at the end of the post. .....
The instructions were to retard the timing 20° and put it in between the firing. Terminals. Then use the distributor to get it back to zero...
So when he fixed his set up.....he made it the same as mine and instructed others to create the same problem I have.....
As you have told me....
Putting it in between the terminals can make the spark jump to the wrong one.


My spark doesn’t jump to the wrong one at the higher rpms.....but it does when I start the car......making it....sometimes backfire out the intake and sometimes start excellent. Either way we know it’s wrong and I’m thinking it’s manufacturer defect.

The center piece is seated and the advance plate is as far back as it will go. I’m thinking the spikes should align and they are clearly offset.
