Vacuum Advance

Warranty on a rubber diaphragm? I only wish the vendors would warranty parts like that.

Mark said they only lasted 30 days. Every vendor know offers a general warranty longer than that.

Thanks for the heads up Ramzi. I know I'd get better mileage with one, but I did the math and if I was going to replace the unit every other month I wouldn't have been saving any money!

Ron,

I cant make that math work either. But Im not sure who is selling these defective units and not standing behind them with a warranty.

It reminds me of a situation regarding ignition switches. I know a supplier who sources their switches from China. Their imported cost is about $6.00. And they have a high failure rate - about 20% (in my book, anything above 1-2% is too high). Because these switches are SOOOO cheap, other suppliers (not us) buy them to resell. Now you have a product sold by multiple sources at the same retail price but with the no quality control standards. The high failure rate makes the consumer think that all Fiat ignition switches are inferior.... Not true.

All parts are not the same. And in some cases (not this one however) you have to pay more for better parts if you want higher quality.

That all said... Ron... If you by a vacuum advance and it fails in 30 or 300 days... call me and I will personally send you a new one. Any vendor who doesnt..... well we wont go there.

Now Im going to get off my soap box and read a story to my daughter before bed time.

I recently replaced my vacuum advance 3 months ago, it made a noticible difference and is still working fine. I hope it doesn't fail but if it does I don't want to keep on buying new ones.

What options do I have if it fails? Can I eliminate the advance module? What adjustments would I have to make? etc.etc?

you can just leave it on, unoperational but the best option is to modify the mechanical advance for more advance

Some of EI distributors have 29 degrees of mechanical advance (supposedly came on carb'd cars), others have 22 degrees (supposedly came on FI cars). Add to this the static advance of 10 degrees, and one can see how the total advance is 39 and 32 degrees, respectively.
One can get away with 39 degrees on stock compression, but I bet it would ping with 10:1 CR. I'd prefer to have the one with less mechanical advance and advance the static timing by a few degrees.
