Hello, I've been trying to get my 2.25 petrol engine running sweet. However when using a strobe to check the timing, it will only run when advanced past the timing marks. Ive fitted an electronic ignition and a new distributor as well as a new coil. I put the advanced timing down to better fuel and the refreshed ignition system.

I put the compression tester on just for peace of mind.

Cylinder 1 50 psi
Cylinder 2 50 psi
Cylinder 3 50 psi
Cylinder 4 0 psi.

So with all the above information where to start.

A psi of 50 on first stroke is not great and zero is well bad. How did you conduct the test. Run us through how you did it.

All spark plugs removed, compression tester screwed into spark plug hole. No choke and wide open throttle.

I would say someone has stolen your piston rings.

Turned over with starter? And did you not get any improvement after 3/4 strokes?
As lynal above and/or valve seals gone walkabout.
