The canisters were set at varying depths by the factory added to the fact that if they were not sunk completely than they can move over time-- By judicious use of a caliper Anton has worked out a shim to control the canister insertion depth. When he was working on mine he installed a shim and then the can so that I no longer need a metal shim or a paper gasket. I now use 1 white o-ring and nothing else.
Here's a link to his stuff:
I'll figure out some questions.
