Topped off my tank took a short spin in town. Returned and found that I had fuel leaking from what looks like a nipple on the side (not bottom of bowl) of the right outside carb. It looks like it should have hose on it. Could be something was left off after carb service? Glanced through Clymer for some clues to no avail. Anyone know what this is? I assume some type of over flow. Should it have hose on it?

Mike,
The FJ carb leak – it comes to us all sooner or later. Yes there should be a length of rubber tube attached to the side of each carb but this serves only to carry the fuel onto the ground rather than the top of your engine.
To fix the leak you can strip & clean the carbs and replace the float valves if needed. Personally I'd first give the carb bodies a good tap with a socket extension and hammer to try to persuade the valves to seat. This has worked for me in the past.

I shut off the fuel run the carbs dry and refill fixes it must time. As will a rough road... Mine seems to be heat related too..
Thanks for the to tips. Hopefully I can avoid a carb removal. I had them completly gone through a year ago.

A wheelie will occasionally do the trick also (tough on fork seals, though). As can riding off a curb.
Don't ask :)
speed bumps , while on the throttle will do it. :yahoo:
when i was going through my carb gushing phase i extended the overflow tubes so that they exited well below the exhaust and out of line with the rear tyre, so when they did act up I really didn't care or have to fix them in a hurry, after doing all the cleaning and adjusting stuff i eventually put in a set of fairly new XJR1300 carbs and used it as an excuse for a few dyno runs and a stage 3 kit.
Installed a drain hose. Pounded on the carbs, drove over every bump I could find. Tried doing a wheelie. Did not leak after parking, hopefully just an anomaly yesterday.
