vacuum advance bad

[virgilmobile]

83 gl1100 poor acceleration.Found almost inoperative timing changes.
This is my story and I'm sticking to it.
Found bearings in the timing mechanism rusted and jammed.Also a hole in the diaphragm.
Fixed both and find a noticeable improvement in acceleration. Took 5 hours over 2 days to fix.
Here's the pix.

OH MY GOD is that's where it is?

Got the cover off and the 3 bolts out

1 hour later and 2 Band Aids

I just had to tear it apart

Here's the hole

Yea,I used Gorilla glue

There is a dark cloud for every silver lining

Virgil,
Did you have to pull the drive-shaft?? or can it be done without going to that extent?

Also, can the vacuum actuator be removed without removing the "distributer" (for lack of a better word for it), or as I see it , it has c-clips and such holding it in place that would not be able to be easily removed without removal of the main part (distributer) first..

I did pull the whole swing arm including the drive shaft.I didn't even bother to see if it could be removed without.It was a good time to grease the swing arm bearings.
Could not just remove the vacuum unit,can't get to the retainer bolt(it's on the top)The vacuum unit was a bear to remove.It not only has a "C" clip holding the control arm to the base plate,there is a "bolt" holding the unit to the housing.Mine had no hex head,I had to use vice grips to get it loose.
