Hi,

Since changing my float needles (to alloy neoprene tipped) I find that the float heights are now 1/4" bellow the top of the bowls.

What effect would those in the know expect this to have on the running of my engine? BTW its a Daytona and I seem to recall someone (Mr Pete?) saying that the floats should be 0.1" below the top of the bowl.

What is the recommended method to adjust the float height. Before anyone asks, No I don't have stay-up floats, there's nothing wrong with the hollow plastic ones currently fitted. As I see it the method would be to drive the brass float valve seats down or to bend the tabs on the floats (where they engage the float needle) up slightly.

I've not had to do it in ages but think that i bent the float tabs GENTLY

The range I use for float height is 0.060-0.080" below edge of bowl, but I don't believe the tabs on the original style plastic floats will hold a bend.

Adjusting float height is normally done by moving the float valve seat. It's a pretty sensitive adjustment, usually done by tapping gently with a soft drift. If you've the inclination, you can make a little jig to make the adjustment in a little more controlled fashion. About halfway down the page:
