what will a broken ignition advance cause?

[zacheriaj]

Looks like the rotor has broken loose. Can you pull it off the top?

It wont come off. isnt the rotor supposed to lock in though not just spin all the way around? I think the little metal tab that lets it do that broke off.

Was there a rotor with the advance you bought? It locks into the notches on the pivots.
What year 550 is the new advance coming from?

That's a different looking rotor than used with the crank trigger plate I sent you.
I wonder what the difference is and will the 550 rotor trigger the signal.

the one in this picture is a common 8/16 valve mechanical advancer even for 77-79 550-1000 suz. points ignitions.
