Default Re: carburetor tuning...

The needle controls mid range. The jet controls top end. There is no richness adjustment for the idle circuit. The choke lever should be up when its cold just until it pops off then drop it down for it to run. This is common to most 2 cycle engines. My old 500 triple had a spring loaded choke so you didn't leave it on. I'm going to start sounding like a broken record in all my posts...but get an NGK B6HS and throw away the chinese spark plug. The higher you pin the needle the leaner your midrange is.
