Parts Wanted Wtb CMB backplate gaskets

[John Dooling]

Hi guys, had a gasket push out on me Sunday at the pond. It’s on a Purple head CMB .90. Any help is greatly appreciated. Thanks.

I know this might sound odd but just remove the gasket and reassemble. Back when I ran those purple head 90s they were known for excessive disc rotor clearance. Simply taking the gasket out and reassembling without it made the rotor clearance much better (and no they won't have an air leak without the gasket). The late Rod Geraghty turned me on to doing that to those engines.

To second what Don mentioned I have done the same and used some anaerobic gasket sealer from Loctite.
