1975 911 2.7 engine. I just pulled the engine again for a broken head stud, and replaced it. I had it out a couple months and when I put it back together the car was running terrible! I pulled my plugs, 3 looked real clean, 3 looked like they were burning rich. 150 pounds compression in all 6 cylinders...
Pulled the fuel distributor apart, it looks like I had water in the fuel and it rusted the shim. I can see pinholes in the shim for three cylinders!
Are these shims available anywhere? Any and all help appreciated....

Thanks John,
It is unfortunate but they give the same excuse of product liability and state "parts not available" - "we'll be happy to sell you one we've had rebuilt".
I'm sure the parts are available...... somewhere.....

Autozone carries the shims for volvo distributors, might have a similar size for the Porsche.

You are looking for the laser-cut fuel metering shim in the fuel distributor...easier to either get a rebuilt and tested metering unit or a used one.

I hope the one I'm building out of a budweiser can works.
Since it's only a N/A 2.7 maybe I should have used Bud Lite...
