I received a 73 220d from a family member who let it sit for 20 years. It will not start. I only have between 200 -220 compression on each cylinder and the delivery valves don't seem to be putting out much fuel. I do have a little fuel to three of the injectors but one is bone dry. The valves were adjusted, fuel filters have been replaced, as well as the hand pump and the injectors were rebuilt.



- Will it ever run with that low of compression?
- Any advice on getting compression up? Wet or dry doesn't get much better, I tried putting some seafoam down the cylinders and letting them soak a bit but compression got no better.

- Any advice on how to get better performance out of the delivery valves?



All I know to try next would be some Restore Engine Restorer and see if that helps the compression?
