idles on choke, crazy bad idle unchoked, give it gas=dead carb issue.

I have spoken with randy about the problem, and im going to post a pic of the floats. notice the direction the tang is bent. the measurment taken in the pic was 21mm,

diaphragms are sound, boots are not cracked, air mix screw set at 3 turns out, which did smooth out the idle.

That is the incorrect location to measure. You need to be measuring at the step on the other side of the float where the rounded portion starts. Portion B in the photo below and I cant tell from your photo, but to the gasket surface as indicated.




The tab should be bent the other direction like the photo above...

im measuring from the lower portion, not the raised lip. it that right? in any case, sounds like im 4-5mm low

Yes, the gasket surface.

Technically you are too high on the float level when based off of the bowl volume. I am going to say it might be more than your estimation based on the arch of the float through the travel and the location you have been measuring.

Oh!! Now you've done it!!! I see another Monkey Made Tool (MMT) here. I need to open my carbs and take a few measurements to finalize the shape. Then open up the CAD app to document it and get some made.  I can't help it, my mind is wired for this shit...

[Goetz]

just adjusted that one and re measured from correct position. I was as 16mm. wouldnt that make it insanely rich, like, when the butterfly valves opened, gas flooded it?

[Goetz]

going to go fix the other three and see how she runs. setting em all at 23mm.

There is already a tool or two.

Yep, there should have been fuel visible flooding around the e-tubes at idle.

Well, now you have more time to polish...

ok, time to annoy the neighbors! lets see if this does it

Polish? Polish??? With 365 days a year to ride why would I waste time to polish??? I knock off the bugs and ride....

[Goetz]

it just occurred to me that old carburated bikes must save riders a fortune in gas and tires...

[Goetz]

im about to light the bike on fire, but i cant, cause itsmy only transpo in a week. so, idled at 4krpm on choke and the left two exhaust headers turned RED they got so hot. thats a lean issue, yeah? what would make it so lean? still dies when ANY throttle is given.
