Yes, mine looks just like this picture. Except the only port that has a hose connection is the outside one away from the engine block. The other one is left open to atmosphere.
I pulled vacuum on the outer one that has the hose connection, and saw no change in timing. Is this possibly the boost retard side? I did not have a way of applying pressure to it to see if it retarded timing.
I checked the centrifical advance and they work. I get about 20 degrees of advance at the crank at 4000rpm . Is this a little on the low side?
