The alternator does not "kick in" It supplies 1/2 wave AC and the rectifier/regulator converts it to regulated 12 volts.

You are jumping to unfounded conclusions.

You need to give more information.
What kind of exhaust does it have?
What kind of intake does it have?

Carbs come LAST in the tuning up process. All other  tune up items must be
finished first, like setting points gap and checking the static timing.
Valve adjustment and cam chain tension.
You need a workshop manual FIRST.   The Internet can help but some info
on the internet can be incorrect. But if you have a workshop
manual you will have the correct information to do the job.
