V-Star 1100 Fuel Overflow Problem

My 2004 V-Star 1100 had been sitting for awhile and was running rough, not wanting to idle and hard to start. I cleaned out both carbs and it starts well but now it is pouring fuel out of the overflow tube. I figured a had a stuck float but I've checked that in both carbs. The when I pulled the tank and air box the left (front) carb has gas puddled in the boot.

I know it must be something obvious but I'm stuck. Does anyone have any ideas on what else to check?

Thanks for any assistance.

It sounds like the float is stuck. Check it again.

Well, that's what I thought when I tore it apart the first two times. I apparently missed something though because after the third attempt it starts well, idles, and runs without pouring fuel any longer. Now I just need to figure out why it backfires from that same front carb/cylinder intermittently.

Thanks for the advice. You confirmed my first thought but convinced me to give it another try which worked for the fuel spilling issue.

Thanks!

Get some brake cleaner and spray between the carb and the intake to see if there is a leak.

I am having the same problem with my carbs. One of the cylinders is running a little rougher than the other. I was told that one was a master cylinder and the other a slave. I know that there is an adjustment in between the carbs but I am not sure which way to adjust the screw. Anybody have an idea?

Sync the carbs

Jimmy C,

You probably do not want to just turn the screw but there is a sync adjustment. Here is a link to the adjustment. Scroll up and down there is a lot of info on carburetors there.

Basicly I think you connect a manometer to a test port and balance the vacume. I think it is a touchy adjustment.
