1991 Suzuki lt 230 ( carburetor issues )

[bowhunter1969]

I recently purchased a lt 230. I knew it had issues but was a clean looking bike.So anyhows.Iam having poor idle ect. When running the engine has no knocks or pings gong on but seem to be have air fuel problems.Almost like it taking in air somewhere and cause high then low revs and slight popping noises.Iam no rocket scientist but did try to troubleshoot the issues.I started with basic airfilter check.Upon inspection the foam airfilter had just crumble by the touch of my fingers.Needless to say its in the garbage now.So next i went into the carb.Had smalls junks of rust sitting in the bottom of bowl.Previous owner said it sat outside for quit some time.Anyhows i check the carb for any clogged fuel and or air passages.All seemed good actually.Now back to when i removed the carb from airbox and cylinder intake.I removed the throttle slide cable from carb and disconnected fuel line from pitcock valve.So next i was getting ready to remove the starter cable from the cap starter plug that screws down into an area on the carb.Needless to say it came loose without have to remove the cap starter plug.So i was like.hmmm???? So i was like what the heck is this cable suppost to hook up to.So i decided to pull up schematics on bikebandit.com.It shows that it hooks to a plunger in the carb there.Well, i never seen no plunger.MISSING..LOL...Could this be my issue? And what does this plunger and manuel cable actually do? I would think without this plunger in place that it could be the air issue i was thinking i was having.Any feedback would be awsome! Thanks

that plunger you are missing is the chock or enrichener. It also should have a spring in there to push the plunger down to shut off the chock.

I sorta figured that was a chock.Thanks. But then what is the other plunger assembly that goes in from the side ( black knob? ) which also looks like a choke. And how do the 2 work together. Or are the 2 just two different method options of choking the machine? The side plunger appears to me to almost touch the spring of the starter cable and or other plunger i was refering to in my first post.

More feedback appreciated please!

that knob is a primer. I only used it when it sat for a long time or it was very cold out

I found a link lastnite on the carb.http://sites.google.com/site/suzukilt230svault/help-how-to-s/carb-tuning....very helpful link.I ordered a carb rebuild kit from ebay and ordered a starter plunger (choke part) of bikebandits just this morning. The plunger has to be the problem surely. As of now it runs crappy and engine runs hot or ( lean ). I will get back on my post in about a week and let you all know what happens...Wish me luck! lol..
