Float height measurement

[POULSEN]

I am rebuilding my carbs (GS 550 '77 VM22).
Everything went smoothly until I started to read.

How do I measure the float height?

The VM Carb Rebuild Papers says: "Adjust the float height to xx mm by measuring.....when the tab on the float just touches the needle"

Haynes says:"The floats should be in the closed position when the measurement is taken".

Clymer and the Suzuki Service Manual just says: "measure"

I'm confused What is right?

This is right... "Adjust the float height to xx mm by measuring.....when the tab on the float just touches the needle"

The reason for this technique is that the needle spring sometimes compresses slightly under the weight of the float thus you need to hold it up.

Turn the carb to the angle where the float is hanging straight down, then turn it a little more until the valve just closes. Measure the float height with the carb held at this angle. This way a wimpy spring won't effect your measurement.

Dont forget the remove the gasket from ure measureing surface as well

Hi Mr. POULSEN,

As Mr. tkent02 suggests, you may not be able to measure the float height with the carbs straight upside down as in the pictures in the link below. But this should give you an idea of what you are measuring. A link from my site:

Thanks to all of you for your help. It is much appreciated:dancing:
I'll get back to assembling the 324 parts:

but it is more fun, if you know you are doing it right.

You counted them all?

Thats a very nice work area. Is that an old tablecloth? I think the grid would help me stay organized.


Thank you for your indulgence,
