Anyone have experience with the Speedway or Ron Pope reversed corvair box? I put one on my 28, brand new from Ron Pope and it had considerable play in it. In fact it was about as much as the wore out original I pulled off. The adjustment screw sticks out a mile on these so I started screwing it in, a bunch, until I got the play out of it. Seems fine now I just hope it seems fine on the road. I'd purchased it a good while ago a long with some other stuff and the only time I had it out was for mock up. Just seemed funny to me that I had to adjust a new box, maybe it slipped through like that?
