Last October we did the same test on the engine and came up with the following results: one @ 160 psi, three @ 150 psi, one @ 120 psi, and one @ 60 psi. This time, with engine warmed up, testing showed two @ 140, one @ 135, two @ 130 and cylinder number two at 45. I squirted some oil down in the spark plug hole and did another check. It went up to 60, so there are still issues. All-in-all, though, the test run was a success since nothing banged, clattered, or untowardly spewed fire. My next move on this will be pulling the left valve cover and checking the rocker arm adjustment on the two valves to that cylinder.

The testing complete, I returned the carburetors and battery to Ringo’s engine compartment. By this point, Mikhaila had finished separating the engine seal retainers from the shrouds, so I released her from working. I, however, still had another project to attend to – this one on Ringo’s distributor. When I’d previously checked the dwell, I’d noticed that it would change with the revving of the engine. In my experience, this indicates a loose pivot pin on the points’ plate. At that time, I’d just plugged the vacuum hose, verified the dwell was holding steady at 32 degrees and moved on. Yesterday, I decided to replace the points’ plate with one that I had removed from Glinda when I’d installed the Ignitor II ignition system a few months back. After the swap, I hooked up the dwell meter, set the dwell to 32 degrees, hooked up the vacuum line, and fired the engine. It would start, but barely and wouldn’t idle. It took me a few minutes to discover my error – I’d neglected to tighten the fitting where the fuel line enters the fuel pump. Sucking air was never going to re-fill the carburetor bowls. With the fitting tight, it only took a few cranks of the engine to get gas in the carbs and the engine running smoothly. Sadly, the dwell still wouldn’t sit still as I revved the engine, so it looks like the distributor shaft bushing gets put on the list for replacement. With a golf tee securely plugging the vacuum hose, I checked the timing – still sitting at 12 degrees BTDC.
At that point I called it a day, put away the tools, and locked up the garage.
