Parts hunting has been good to me lately. About a week ago I scored another set of 33 Mikuni smoothbore for 150.00 shipped... I have lots of extra parts now, so I started the rebuild process. I found 3 out of the 8 brass floats with the outboard side Concave. All the others are convex. Are they still useable or am I lucky I have 5 out of 8 that are good? Also two of the bodies have a needle bearing pressed into the throttle shaft bore. I don’t want to remove it for fear of damage. Will it be ok to soak in Berryman’s
Those are finicky carbs Matt and no ports for syncing and the bigger manifolds didn't have them. I had a set years ago that the piece was cut-off the bracket just like yours. It's a push/pull set-up and for some reason people like to cut-off the return boss? Maybe they are loosing weight to go faster, ha. Make sure to replace the gasket under the removable slide holder or you won't get a proper signal for pilot system.
Mikaw: I would try your countersink on something unimportant when you get it and see how the angle lines up with the jet. A bit of machinists dye or even a Sharpie pen may help see how the angle fits the jet.
