Weird, sudden AFR issue Proform 750cfm!

Try what's been said.

Make sure you didn't lose the check ball or pin that goes under the shooters... you can end up with siphoning... do you have a needle and seat leaking onto the blades at idle?

DING! DING! DING!

Had to climb up and squat on the inner fender with a light, but I FOUND IT!!!
Front shooter is leaking around the base!
