MSD doing it again
Same ignition,new problems!The timing advance is not working like it used to.On my road tripp home i noticed the timing issues ar higher rpm,played w/the dizzy for a while and found the advance weights were slightly corroded on their contact points and were sticking a lil.cleaned them off,threw a lil dielectric grease on all contact points just for good measure.
Well another hundred miles or so now the advance is stayin all the way open,sometimes very slowlyvery slowly going about half way back or so.
I played with it and the timing light for a while and finally cut 2 rings out of the light spring, allowing the advance to return about 90% of the way...enough to finish the tripp anyways...
So do these springs loose tension often? or am i looking at the vaccume Advance Mechanism on the front of the distuributor?Or did i manage to break it myself?
Inital timing is at 10 Deg, 25Deg bushing in the dizzy,one heavy,and light silver springs.
im ordering all parts anyways, make shure i get back to work.sry for the book,just curious if anybody else had simmilar problems

Are you sure don't have vacuum on the vacuum advance at idle? if so, it's holding the vacuum up. That can be caused by the throttle plates being too far open, or using the wrong port.
