This looks cool...

Interesting, BG always preaches to set the idle screw(s) so .020" of the transfer slot is uncovered and leave the idle screw(s) alone. They say to use the idle mixture screws to find you proper idle. It works that way but goes against convential thinking when tuning a carb... With this maybe they'll remove the large idle screws and make the throttle blade adjustment less accessable.

Is that it in the center of the baseplate? Another screw to fall in the intake??

Its on the topside ofthe baseplate soit couldnt fall in, its accessable through the air cleaner stud hole.

they had to do something to make them idle...lol
