Yes!  If I understand correctly you are planning on putting a magneto with a fixed cam ring and auto advance, in place of your manual A/R magneto. Of course you will lose the manual A/R facility. If you have to use the manual A/R when riding, maybe because the bike pinks under load, you will have lost the ability to overcome this. If you never use the manual A/R, other than for starting, you may not notice the difference.

You can keep the manual facility working, after fitting the auto advance.

The benefit of fitting both auto and manual A/R is that the ATD automatically retards the timing on start-up without weakening the spark (the manual A/R weakens the spark when you retard the lever), but you can still use your manual setup to deal with pinking under load. I didn't mention this in my reply because rockthedog doesn't have the option of both unless he starts mixing and matching bits, which is not recommended!
