Adjusting the valves, quick and short questions., NOW I need help on timing !!!! PLEASE Options

[913B]

I am checking the valves because they seem noisy and also to track down an erratic idle
I have read the rocking method but I would like to stick with the dizzy and TDC method please.

I read cyl #1 & #3 has same TDC and #2 & #4 has same TDC

Question 1 – Setting TDC on the fan notch does it have to be at “0” or will the notch for “27BTDC” work too

When I find TDC for #1 on fan notch and dizzy rotor is pointing to #1 tower of dizzy cap

Question 2 - Can I adjust all the valves for #1 and #3 cyl ??
Then rotating the motor to #2 TDC on fan notch and dizzy is pointing to #2 tower

Question 3. Can I adjust all the valves for #2 and #4 cyl ??

Question 4. Is it wise to replace the cork valve cover and not risk a leak.
The gasket is pretty new though and low mileage since I last had them off.
I am thinking of purchasing the 914rubber re-usable ones. Any recommendation’s

Thanks everyone !
Ted

Cap'n Krusty always said that the tab that sticks off of the one end of the cover is supposed to be on the bottom, which would put the VW logo upside down. He never said why though, at least not in any thread I've ever come across.

I've read that other people have said that even though the cover looks symmetrical, it actually isn't. I've never looked closely enough to say if that's true or not.

But yeah, I've never come across anything that says exactly why. There must be SOME reason for that tab one the one end, if not just to be there for a directional indicator. (IMG:style_emoticons/default/confused24.gif)
