Modern Vespa

Anyone know if they make thumb screws (i.e. "toolless") for the air/fuel mix on the KEIHIN CVEK-2600A carb on the LX-150?

something like this thing here?

McMaster.com has a wide selection of thumb screws. Surely one will fit the air/fuel mixture screw.

But do you really need that kind of adjustment? It only controls the mixture at idle, and typically once it's dialed in there should be no need to readjust it. The other screw, the idle speed screw, does often need adjustment seasonally.

Yes, something like that. I saw that was for Kehien carbs, but the Vespa wasn't on the fittment list so I didn't know if it would work.

it should work, but without it listing the specs I can't say. honestly I've never installed one on a keihin but have seen plenty on 2T dirt bikes and china bikes. so at 8 bucks it's kind of a gamble.

but I have to ask why? usually setting the mix is a pretty much one time deal and doesn't need constant attention.
