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 !

You have to make a mark on the flywheel. While under the car, reach up around the trans and find the top hole like the bottom one. Rotate flywheel till you can feel the notch with your fingertip. Put some white paint on the flywheel thru the bottom hole. The engine is at either 1 or 3 when you can see the paint. 2 or 4 when the notch is visible. The crankshaft rotates twice for every engine revolution. I'm not sure cause I haven't adjusted valves in a while, but I think your turning the wheel the wrong direction
