Evo carb
Another tip is replace the jets with brand new ones... I saw a jet wear down on an S&S carb to where if you took a needle out of a cv carb it was out 1/4 on the new one, and 1/2 on the used one.. Improper metering. they DO wear out! Look up jetting on google for whatever carb you are running. Or just go buy a few different sizes close to what you have. The main jet is the one that gets the most action and wears the quickest from what I have seen. Trucker Gary

Follow the instructions miacycle gave you carefully and as mentioned take a good look at the float fuel valve or get the rebuild kit and replace ii to be sure.

they have a lot of goodies for the cv, if you change your needle to the N65 you will have a lot easier time tuning and won't have to mess with clips.
The cv carb is pretty easy to work on and understand, take you time and it s a fun and easy job rebuilding them.
Cheers

I use Windex to lube them. Works good. Also good for removing rings from fingers that have swollen.

I don't think this was mentioned, but you may want to replace all of your fuel lines. They can degrade in time and little particles will clog your jets, making it a headache to diagnose over and over. For no more than new fuel lines cost, it just makes sense. Also, if your still having problems with fuel overflow, your float may not be positioned correctly, you can bend the tab on the float to raise or lower the fuel level in the bowl.

I bought a rebuild kit for my cv a while back. After installing the new float needle, fuel over flowed. I fought with that problem for two days. I finally just put the old needle back in, ridges on the rubber and all. Problem solved. I have no idea why that new needle would not work. When I laid it side by side with the old one, there were a few minor differences, but nothing to prevent it from working. It had me stumped...still does. A guy gave me a cv he had around from an old bike. That carb had the same problem, I could not get it to stop over flowing. It's a puzzle I never solved.
