I assume this is for your MK1? Do you think they will refresh your vacuum advance unit? Let me know what happens!

I hope to find one! I wouldn’t want to send away my only one either. It appears the small chamber advances timing as well…not sure how much compared to the larger one

I just looked it up in the turbo supplement. When checking the advance, it says to apply vacuum to both chambers separately to make sure the breaker moves. Then it says to apply pressure to the smaller one. It seems the smaller one does both. Not sure of the function of the larger ported chamber. Si...

Thanks for the reply. Yesterday I removed the vacuum advance and realized it was an advance from a metro! I put my old one on and I was able to set timing with and without vacuum. The problem is that the diaphragm from the ported outlet is ruptured. You said this chamber (larger one) is responsible ...

Hello! I have an 88 sprint turbo. I recently did a LOT of work to it. Now, my timing is advanced off the scale, like at 30. As is, the idle quality is ok and revs happily (no road test yet). Let me first say what I did and checked: -Timing belt: crank and cam sprockets are aligned. Woodruff key etc ...

Very cool! I was having a hard time finding some for my factory turbo...I think I sourced one, but the business was iffy and the price was steep. Mine were decent so I sprayed a few coats of permatex copper gasket spray and hope it seals. The more I dig, the more problems I find! What do you cut the...

The AC idle up has the vacuum solenoid separate from the adjustment portion. In the last pic you can see the solenoid on the left and where the AC valve would mount. The electrical idle up is next to it and has the solenoid on it. Next pic shows where the AC valve mounts. I do have a spare valve. I ...

Well, I’m in Washington, up near Tacoma. I know that’s not super close…I believe there may be a few people there from a group on Facebook called NW Odd 1s out. There is also a guy in Vancouver, WA with a turbo sprint. He is on another Facebook grout for geo metro/sprint enthusiasts.

The headlight is good. Let me know if you want it.
