I just noticed the base on my Projection TBI unit is slightly warped where I believe it won't seal. Anyone have any idea what I can do to fix it. Or where do you recommend I send it?

How badly warped? It has to be pretty severe for it not to seal with a gasket.

I take it back it looks like the 1/4" phenolic spacer I just bought is warped. I guess when I install everything I'll check it with a flashlight and the blades open? What do you think?
