Super Beetle in a good mood

Combustion note of air-cooled VW 11 motor sounds me so comfortable as I had adjusted valve clearance firmly at the standard value of 0,150 mm the other day and also mixture control was adjusted a little bit leaner, but cold morning as it is today, still a bit richer condition now. As for backlash in steering linkage, the tightened gear box adjuster well contributes to establish desired straight running stability. I mentioned before about the inconvenience in the spear gear box parts that had critical wear on the strict cross shape connection in steering universal joint, so, careful checking is necessary also on the same portion of my 1302 Super Beetle, because that point is always exposed in outside air, some lack of lubrication is imagined? Some stingy idea comes up in my mind, even a worn universal joint parts may survive again if the worn space might be compensated by a piece of thin metal plate that is utilized from any spiral thin ribbon spring plate made of hard iron plate, just the elimination of backlash is important, no?
As a conclusion today, all the mechanical moving parts should be lubricated adequately all the time to avoid inconvenient wearing and friction resistance loss, to prevent rusting.
