I'd like to lock out the advance on my accel dist. Do I just wire wrap the spring posts??? Do I tack weld the weights???

Thanks,

Scott

Scott,

Isn't an Excell a stock rebuilt dist.? You can remove the weights and dril the plate and insert a screw to prevent the centrifical advance from moving. Then time it and you'll be "locked". Some people use epoxy instead of a screw.

That's what I'd do if I could get the top all the way off. The mag sender is locked onto the shaft pretty good so it's tough to get to. I zip tied it for now just so I could keep on working on the timing system.

It's not a stock dist, it is a magnetic setup.

Thanks,

Scott

I took the weights out of mine and drilled a hole down through the plates and tapped it with a small tap then inserted a machine screw with a little red loctite. This worked great on my car. Good Luck!

Scott,

If you can't get the sender off the shaft, then do it from the other direction. Take the gear off the bottom of the shaft and pull it out the top.

I knew there was a reason I hang out on this board.

Thanks Steve

FYI, I pulled the gear and bushing off the bottom and had easy access to the weights. Drilled them out and tack welded the plates together. That ought to keep things from moving around...

The mag sender shouldn't have to be pulled off. If you take the little stuffing pad out of the center of the shaft where the rotor slips on, you will see a small clip down inside the shaft. This is how to remove it on a stock Ford distributor.

I really have to admit my ignorance here. What is the advantage of locking out the mechanical advance? My FE has a 4150 with a Proform carb body, so I don't have vacuum advance any longer. There's no way I can jack up the initial very high, so (again) what is the advantage?

I'm locking it out because I'll control advance and retard using an MSD timing control box. All I need from the distributor is the timing signal. The box determines advance based on the slope I program into it. It also retards on stratup and when I squeeze it so it doesn't detonate. Nothing like a little nitrous to clean out the pipes.

The other reason for locking out a distributor is for a race car that never sees anything under 3500 rpm with a load on the engine. They idle crisp at full advance and you don't have to wonder if the timing advanced or not. Some use a timing retard to start, and others use a seperate ignition switch that they can turn on after the engine is spining on the starter. Our '66 has a stall of over 4000 rpm and it's fine with the timing locked out. Idles great too,
