Distributor Vacuum Diaphram
« on: August 11, 2003, 06:50:38 pm »
I have recently discovered that the inside diaphram on my vacuum advance is shot. I discovered this while checking the timing and noted that it was jumping from 10 to 20 deg. I would assume that the breaker plate (original distributer) is now able to move slightly since the diaphram is shot. Question!!! Does anyone repair these or sell a good replacement. I suspect that some of you have already had this problem. I have currently degreed the damper to 40deg and adjusted the advance to 37deg at 2500rpm.While the timing floats from 10 to 20 deg at 850RPM..Suggestion anyone.. It seems like it is always something with this car,but you have to love it..

Check with Mike Ulrey 727-644-9851.  He is very knowledgeable about Boss distributors, including the vacuum advance.  And will repair them..............Dave

Instead of fixing my failing diaphram, I converted the inside of my dist. to a 289 HiPo mechanical advance setup. The problem is the arm on the advance unit is in the way. I found an old advance on Ebay that had the arm already cut and used that and kept my original '69 unit to be rebuilt someday. I got my parts from Mike Ulrey in Fla. I remember the cost being around 20-25 bucks for the parts and about 40 for the advance. I don't remember the cost to rebuild the advance, but I think it's plenty more than that. Anybody know for sure? I did this more for performance than anything.

Just talked to Brian and he said he charges $75 to rebuild and replate the vacuum advances. I have had him do several and they look like brand new when done. Mike rebuilds the distributers, carbs. trans.,and more.
