Hi all.
Last weekend I did a little work on my A4 - new belt tensioner from MMI, re-epoxied the water jacket breaches (last time before considering a new short block), and adjusting the tappet clearances. According to two of the three manuals that came with the boat (unsure if any are related specifically the "rebuilt" 1967 block engine without visible serial number), the tappet clearance settings are different than standard practice here. Unfortunately, I set the tappets per 2/3 of the manuals without checking the forum first. Of course, today I couldn't get the A4 to start. Lucky to have good access to the valve side and only had to remove the carb to get at the cover and tappets. All set to E = 0.012 and I = 0.010 COLD. Starts and purrs again. But why the different values in the other manuals? Here is the proof.
Both list the clearances as E = 0.010 and I = 0.008 COLD. "Archival Manual" I guess...
