I have a few questions about my 998cc 1990 Mini Mayfair
So, at current the overflow pipe on the float chamber for the HS4 carb has a simple vented plate over it rather than the pipe, as a lot of people do. The metal pipe from below the sub frame is still there just disconnected. Is it better to have the overflow pipe connected or not? I'm thinking to keep the plate as if the carb is working just fine it shouldn't cause problems and if not, then the plate will raise the problem quicker, albeit a bit messier.
The second question is about engine breathing, right now it has a canister from the timing chain cover that is connected to the carb and no signs of having a breathing canister at the crankcase as the mounting point is solid. Is it better to just keep this setup or think about upgrading it to a case that can have a breathing canister fitted there as well - baring in mind it will be daily driven one day. And finally could someone explain the setup between the two breathing canisters and the carb using a y-piece.
Still learning my way around my mini so thanks for any corrections or help!
