Carb float height

[ttfraz]

Hey guys so I was rebuilding my carbs and I used the guide from basscliffs site for vm carbs. It's a great write up the only thing I'm not quite sure about is setting the foot height. So it's from the edge where the gasket to where? The top of the black float? Is it upside down or right side up. Also which tab am I bending the one that goes to float needle right? Haha I could just be missing something but pics or a better explanation would be nice

You measure from the edge/lip of the carb body to the top of the float (the black round thing). Do not have the gasket in, you are supposed to measure from the bare aluminum. What you want to be looking at is the float needle as the float tab touches is. Stand the carb up properly as if it was on the bike, the float needle will come out as far as it can, then slowly tip the carb over (upside down) but not fully, you are watching the little tab on the float arm to where it just makes contact with the float needle and seats it. if you look at it a few times you'll quickly see how it all works. It's that tab on the float that you bend one way or another.

You can see the small tab in the middle of the float posts, that's what you bend. I usually have my carb body setup on the bench at an angle, and slowly let the float lay onto the float needle while watching it. When I know it's where it's supposed to be I measure the height.

Just remember to not have the gasket in there.

If you floats look like these, where they are plastic and have that flat spot on the bottom where the brass hinge mounts, then measure to the top of the rounded part not that flat on the top. Hopefully yours are cleaner than these... Sorry don't have and after picture.

If you floats look like these, ...

Well, he did say that he was working on some VM carbs, so they would look more like what azr posted.

The VM carb floats have a notch on one side of the circle. The notch faces "down" ( up when installed on the bike) so there shouldn't be any confusion in where to measure to on the float.
