Good to hear you've had success in getting it running. Now, to further use your compression tester do this; after getting the engine up to operating temperature, pull the plugs, and with throttle wide open, perform another compression test. The numbers should have come up some from your earlier readings. Check cyl #1, then using an oilcan squirt a bit of oil into the cylinder. This forms a bit of a seal around the top of the piston and should improve the initial reading. If it has no effect, it indicates it's a valve problem. Check each cylinder in turn, firstly as is, then with a bit of oil squirted in. Performing this test, this way, will immediately illustrate the condition of each cylinder, be it rings or valves. Report back with your recorded figures. Enjoy, you'll be learning heaps with this car.
