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

I agree that "the crusty method" is the quickest way once you understand the basics.

But trying to teach someone the shortcut, before the 'longway' makes for less understanding.

The first time I tried the crusty method, I thought that "rocking"meant the exact opposite of what was intended so it was 100% confusing.
By understanding the text book method first, it will help you appreciate the shortcut.

There was also the long debate about the backside of the lobe not being 100% consistent, so I would get some variation based on where on the backside of the circle you set the valves.

Maybe it's just easier to notice that when you set to zero lash.
I can set it to 'zero' on the back and find spots on the elsewhere on the backside that are not zero.
So I just choose to use a repeatable measurement - TDC.
