Valves need adjustment? Options

[Mikemo44]

Hi All, Long story short, I bought a 914 with two turbos strapped to the back and a Holley EFI installed. It never ran well so I decided ditch the turbos and try carbs. Prior to installing the carbs, I took a shot at adjusting the valves as I thought that might be contributing the car running rough.

Now with the carbs installed, it seems the valves in cylinder 2 are off. Lots of knocking and exhaust coming out of the cylinder 2 carbs.

Is this a valve adjustment issue? Or something else like timing?

Much appreciate the help.

Compression test.

Leak down if trouble seen in comp test.

Possibly correct valve adjustment???

recheck comp/leak down tests

You have what looks like intake valve not seating correctly on cyl #2 to me.

My money is on wounded engine, but you might get lucky...



I'd LOVE to see the twin turbo set up on that.

It would need tiny little turbos.

4 head bolt air cooled design is less than ideal with boost, but a mild system done perfectly might do OK.
Two baby turbos would be interesting...
