Ok so I have changed the distributor out and before I run it I want to check and or adjust the timing. I have three questions that I seem to see some conflick on when reading all the info provided and info from the guys on here.
Enging, AQ120b 1979 with points and condenser.

What will be my intial setting?

What will be my total advance?

what will be my total curve and how many degrees?

You have to run the engine to set the timing. Just remember, you have to set the dwell before you set the timing.

All the timing and ignition specs are in the service manual I gave you a links to.

Re: Timing on a volvo penta AQ120B

timing is about 10 degrees @ 750 rpms

Strobe setting 21bb or so degrees @ 2100 rpms

Strobe setting 36 or so degrees @ 4200 rpms

Dwell angle is 64 or 65 degrees hard to read super accurate since I bought the non digital one!

Not too bad I think.
