dual point distributor weight question

My car wont idle , just noticed both weigths in my dual point distributor are loose.
They are held in place by the stud at weights end.

Advance opens freely by twisting with my hand and comes back to initial.

Anyone have a picture of the inside of a dual point distributor so i can compare what is missing

thanks

Re: dual point distributor weight question

MSD distributors are based off of Chevy points distributors. I don't know if this kit will work, but you could try it. It has teflon bushings that may fix the problem.

Here is the MSD site. It takes about a day to get registered so you can post. I would post a thread and let their techs answer. Just disregard when they recommend buying an MSD distributor. Or, better yet tell them you want to build an "undercover" distributor that looks stock from the outside using MSD parts and see what they say. That ought to catch their attention. And if you end up using MSD parts it won't be a lie.

By the way, I am not a fan of MSD distributors even though I run one right now. Too many production problems...

Just thinking about it a little more. Get a tach and a timing light and plot your ignition curve every 500 RPM. It is a good idea to do from time to time anyway. Maybe the distributor is advancing fine now and just looks suspicious...

They all have their ups and downs. A dual point will survive voltage spikes and other troubles where the photo and magnetic won't. Overall I prefer the magnetic.

My old Mallory Unilite was the most accurate and best built. But you have to have a strong electrical system with good grouns to run one. The Mallory failed when the wiring harnes vibrated its way up into the rotor. It took a couple years for it to make its way. It sawed right through the red green and fried the pickup.

I run an MSD Pro Billet now. The advance curve kits suck, and the bushings aren't very good. MSDs rust like mad. I had to drill holes in the cap to vent and that only lessed the rust. Check MSDs site and do a search for rust!

I haven't decided what type I am going to get next time. I am thinking about getting the Crane electronic advance distributor.
