P4120701 Small Block Mech Tach drive

It's just going to full advance when it's running, needs stiffer springs I have 2 of them at the moment I had 5 last year, it's a great distributor. With the cap off can you turn the rotor a little if so it's not frozen. I set the balancer at 5* BTC them line up the pickup with the reluctor point and lock it down, that is your starting point now check your max advance and see what you have.
