Hi Kenny I have a cliffy installed but not fitted recently. Difficult to see feel but I assume its where the metal scoop mates with the subway ramp but not sure.
If it’s been previously working with the cliffy then I’d look at the gradual distortion of the metal scoop as it gets pounded by balls. It would be great if there was a cliffy which had an integrated strengthened scoop that didn’t bend back and upwards to the point that the snackbar roof annexe gets stressed to the point of fracture. Either that or pehaps the subway has moved slightly?
Issue resolved, I must have overtightened the lower scoop and 2 out of 3 balls were getting caught on the cliffy tab, backing off the screws a couple of turns does the job.
