Questions on Timing and Compression

[Janiel]

What compression should each of my cly's be reading at?(psi) Also could my engine have a problem with timing? It has no power and top speed is 80mph. Oh yeah very bad gas mileage.

If you think you timing if of best thing to do is get a timing light and check it.

Its always a good idea to check timing.

I think(not 2 sure) that the psi should be aroun 175. Time to dig out the ole' manual
