I am working on a nearly new Toro Super Recycler stow and go model with a 163cc Briggs. 1000 series engine. There is a gas tank venting issue. This model has a larger gas cap than most of the Briggs walk behind lawn mower engines. It seals with an oring on the ID of the gas tank neck. It fits very tight. The tank is not venting causing the engine to be starved of gas. I am trying to find the vent and can not. It does not have a tube that runs in to the air filter box like many have. I am looking in the cap for some kind of tiny hole or passage way but can not find one. I see nothing in the vent neck that would constitute a vent of some kind. What am I missing.

If fluid gas has entered the charcoal canister it turns it into a solid mass which basically requires the replacement of the cap.
The cap is #84004416 which replaces 594061. I do not see any vents in it. I respect your experience but I have no idea how this can work. Look at the cap in the link and tell me if you still think that cap has a charcoal canister.
