Centrifugal Advance Sticking
 
I've been through 2 different GM mechanical advance spring and weight kits so far, and can't seem to get any to work! With this accel kit I've been using recently, every time I tighten the rotor down completely (which is just until the bolt head contacts the rotor and I feel resistance), the mechanical advance just sticks. I can force it forward without effort using my hand, but it won't spring back unless I give it a push. All I have to do is back both the rotor screw back a couple turns and the advance springs back smoothly again.

On another note, the $15 accel kit I bought was advertised to make 24 degrees at 3000 rpms. With light springs I make 4 degrees at around 2500 rpms, and with one light one medium I make about 8 degrees at 4000. At least the $5 summit kit I had before actually worked... (tired of Chinese crap metal)

What kit should I buy to just get the timing over with? I'm tired of the problems that come with saving money. I just want 24 degrees at 3000 rpms.

The stock hei weights are just fine. Just Change the springs really. What are you trying to accomplish? Trying to limit max advance? Get timing in sooner?
