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 !

Thanks for all the help everyone.

I lined up the notch on the top cutout and then painted a mark on the bottom cutout.

Now I can hit all the TDC by rotating the wheel (corrected: forward direction), whenever I see the paint or notch at either the top or bottom cutout, the TDC comes along for each cyl and I also confirmed it by rotor pointing to the cylinders 1-4-3-2

So when I was at #1 TDC, notch showing on the top cutout, the TDC mark at the fan is close by maybe off by a few degrees. So how can I compensate for this when I am trying set timing ?

How do I time it using the notch on the top, do I point the timing light to cutout in the rear of the engine instead of the fan ?? The notch would be TDC - "0" though but I need to set it to 27BTDC for my 1.7 and there is no mark for that on flywheel or is there ?

Much appreciated !!
