Varying Intake Disc Rotor Housing
I have a Webra .61 with disc rotor intake.
What would happen if the holes were slotted and you are then able to retard or advance the housing?
Could this be a way to fine tune the engine?
What had me wondering is this looks like it is drilled a little off location radially.

Buy a tube of "Hylomar Blue Racing Formula" (it has to be the racing formula to be methanol proof) and just leave the screws out and try it... 
I bought a couple tubes of it off *bay because I was too lazy to go hunt for it. The stuff is amazing, it never hardens but it seals and holds just about anything. (you can always get it off)
You could run a small bead around the rear plate and let it sit for a while and run the engine.
A friend of mine is a Ferrari Mechanic and he gave me a tube. I've never looked back. He says that it can go through an oil pump and not hurt anything unlike silicone sealers that harden and can clog. Kinda important for him.
I use it on carburetor to case joints, muffler to case joints, a tiny bead on your needle valve threads, it's also a great low strength thread locker for servo screws, etc.
It's pricey but the stuff has no equal. About $9 a tube.

RE: Varying Intake Disc Rotor Housing
Kind of the way BW was thinking but if you modify the backplate so it can be rotated a little with the screws loosened you could then adjust the intake timing. Someone gave me a beaten up example of one of these Webras and the intake is at the bottom left corner instead of the more normal upper right. None of the backplate screws go into a transfer port so they're not needed for sealing anything off.
