A quick tip for adjusting the valves on an air cooled VW.
Set the engine on the TDC marks. Now look at the valves on both heads.
When you are TDC on #1, there should be clearance on both intake and
exhaust on #1 cyl, the intake on #2, and the exhaust on #4. If you are
on TDC #3, there should be clearance on both valves on #3, the intake on
#4, and the exhaust on #2.
The valves CAN be adjusted in these positions, but adjust the valves on
the off TDC cylinders (#2 & #4) about .001" looser. .007" instead of
.006".
This is not a factory procedure, just experience, and something I picked
up from other mechanics at VW engine school.
