Weber IDF Float Levels

I just finished reading George Brown's treatise on IDF float levels (in the knowledge section).
My question is, when measuring the distance between the float and the bottom of the carb top, which float are you measuring.
The float furthest away from the needle valve drops significantly farther down than the closer one.

Thanks

Dave

Dave, the floats should have the same "attitude" relative to the carb top when they are properly set. With the floats off bend/twist the metal float support until both floats are parallel to each other and the tops will both rest evenly on a flat surface (floats upside down).

Then use/bend the two float tangs until the "top" and "drop" measurements are correct - don't twist the float support while you make the height adjustments. Then when correctly set the floats will be parallel to the top lengthwise and the float farthest from the float needle and seat will be 10 to 10.5mm from the top. Try to get both floats the same. When measuring, hold the top such that the weight of the float doesn't comress the ball valve spring in the float needle.

Thanks for your response George -
Okay, I understand the top measurement, but what about the drop - as I understand it, it's 32.5mm.
32.5 from the bottom of the carb top to what? The float farthest away from the float needle drops significantly farther down than the closer one.

Thanks again

Dave

Measure "drop" to the top edge of the outside (lowest) float. I set IDF"s to 20mm "drop" to reduce float blowl slosh during hard acceleration, braking, or cornering; drop setting is not as important as "top". Slosh can make one carb go rich while the other goes lean.

Thanks again George.

I have a new question about the lower main idle screw seats on the 44 IDF Weber.

Is there a specific setting on how much the seats should protrude through into the bores? It has been rummered to me 0.100 thousands. that's a schose under 3/32 I think?

Please set me straight on this one. Is this very critical, or is it another goose chase .

When I spoke to the fellow at Headflow Masters to get a price quoat and mailing addresss he suggested checking them.

Not one of them is the same, all are different.I did as he asked But it didn't help.

Barry, ask Art Thraen - his email is acevw@aol.com.

I contacted WEBER, something is commig with a spec.sheet
