After cleaning, what are the initial turns after you seat them, how
many turns out of the idle mixture screws to start out with?

Yours has the feedback carb working right?

That means you seat the idle screws and back them out about 5 turns and
get it warmed up then set the idle speed to 650. It might smoke a
little.

You then turn the screws in in 1/4 turns at a time each and rev it.
Keep doing this until the idle drops and the engine starts to rumble.
You then back them out until you get the fastest idle. You then are
supposed to bring them back in 'just' until you notice a slight drop in
idle or 50 rpm max.

If this takes longer than 3 minutes to do, you are supposed to rev it to
2000 rpm in neutral for 1 minute to reset the computer and O2 I believe.

This should have the pins at the back of the carb cycling around the
center of their movement.

Yeah, it has the feedback carb. Thanks a lot for your help, this group
is pretty neat, I am new to it, but it has helped me out tremendously.
Thanks again.
