Actually, I did the tests before doing any driving and detected a consistent 210-220-230 compression at cylinders 2, 3, and 4 (3 being the suspect one). I didn't bother to remove the alternator to get at number 1 cylinder, however, my own testing seems to show that compression is quite consistent, with the variation less than 10% and seemingly not the worst in 3. If the valve was unseated, it must have re-seated itself, or, it is also possible that the test was incorrectly recorded. At any rate, I tested it myself and am satisfied with the results ... hard to say. However, I did have some trouble with the Moss TR-6 (and therefore also Midget 1500) rocker feed kit, as a critical bolt broke. However, when tested (it leaked but supplied oil at an excellent rate) the kit solved the problem of insufficient lubrication. However, I do not believe that the lubrication was the only reason the pushrods failed, as they show that they aren't worn out, but rather fatigued to failure. As soon as I get the replacement bolt, it will be a running machine.
Conclusions: In the Midget/Spit 1500, oil feed is insufficient, due to whatever reason, without the auxilliary feed. Also, stock pushrods are of solid construction and are most likely suited to high performance applications, as they seem to have been barely worn after 77,000 miles and are suitable for re-use in a rebuilt engine.
