Here are some shots of my Frankie, I think a lot has to do with the angle you are looking at. I know hits register 95% of the time on him it will take a nice hit to make him reach contact so don't expect any dribble shots to register, he'll just blow those off.

Pull the e-clip off (#9) of the bottom shaft (#6) and check the angle of Frankie's support (#101). If it looks greater then 100 or so, try every so gently to move it back to an angle just about 100. I say 100 because I just checked and it's not a perfect 90 just slightly greater then that. Maybe even 95 but it shouldn't be real wide open past that you'll have to judge when you see it.

Needs to go into that slot for sure, that's one reason why he is leaning a bit too forward for you.
