Compression Test Results
I have been trying to get my A going again after a few years of sitting around. It ran okay in the fall of 2015, but the following spring/summer, it was having issues going up anything but flat road and I didn't have time to really work on it.
I drove it up and down my road after getting it started last week, but had some pretty bad hesitation/missing under higher load/throttle in first gear. The last time I drove it around, I set the timing and gap on the points. It has a new ignition coil and the spark plugs are also basically new. I did a compression test on the engine because as far as I could tell, the ignition should be working correctly. The results weren't so great: Hot: 39/36/30/36 psi Cold: 40/35/30/36 psi Cold with a bit of oil: 40/35/35/44 psi These numbers seem quite low. Are they low enough to account for the poor performance in first great or should I re-check the ignition side of things? Maybe fuel related?
