Float level adjustment

[oz1961]

Hey guys
Thanks always for your help

I have rebuilt all my carbs and read the manual for checking the float levels

which requires removing the carbs and adjusting if not correct

my question is
Is there a way to set the float levels prior to fitting them back on the bike?

thanks again

Yep.

Huh,saw the measurement & thought that's the approx.seating depth of a factory made 9mm.

Thanks for your reply and picture
I’ll try and measure it today but the sight of the circle is a great help too

The casting circle gets you close. But a wet check is really the best way.

I use a digital caliper to get them all at 1.125" between the inner float bowl to top of float. Wet level always checks to 17 mm which is the leanest you want to go. I'm sure @dannymax could tell us about his ingenious self-made tool. Right Dan-o? Hehe.

Not so ingenious Mark-o just a piece of plastic trimmed to the correct dimensions. But thanks for the compliment.

You could use a notched piece of whatever you wanted, as a sort-of 'fits this distance' gauge so it's easy to slap that sucker up, and pry the float tang until you have the distance you need. Kind-of what I use when lobster diving here in FL.

Hey, that's the 'dannymax' method!

I believe he's also corrected for temperature variations, using a 'wet-bulb' measurement, for material expansion/contraction, and ozone levels.

I made a gauge from a piece of hard plastic (part of a tree from a scale model kit) and cut it to help me set my floats at 1.115". It might be partially luck but by doing it this way I have never had to pull it back apart to readjust a float.

I live at 4000' and I almost never go any lower than that, so keeping this on the leaner end of the spectrum has proven the right move in my case.
