Left side puking fuel out exhaust

Post by twofest5 »



I just rebuilt my carbs and the rt side is perfect. The left was pushing to much fuel out so I adjusted the floats. Stopped puking fuel out the exhaust but the #2 cylinder stayed cold and it smoked so too much fuel on that cylinder because the plug was soaked. I readjust that float and now it pukes fuel from the exhaust again. ... puddles on the ground. When I Rev smoke goes away and it smoothes out. At 4000 to 7000 rpm. I'm at my wits end here.

Need more details on the carb rebuild. Did you follow Mike Nixon's booklet or Randakks Video. Even sone Honda mechanic cannot not all get it right. And what did you use for a kit. There are big difference in kits. Pistol Pete is an excellent business for carb rebuilding.

What Fred said, but I'll hazard a guess that you used aftermarket float valves. With the bike idling on the center stand, you may see gas leaking back into the plenum from the offending carb(s). Float height really needs to be set at the height the manual says in order for these bikes to run properly. This is assuming (!) your ignition has been gone through and is working properly.
Keep your expectations tiny and you won't end up so whiny.

A hole in the float can do that. Maybe if you pull the carbs again, you can remove the float and shake it-there shouldn't be anything inside.
My exercise bike is a goldwing.

Hi, how did you fix the problem? I'm having the same issue.
I have not touched the carbs at all since I bought the bike, but it's been sitting for a few months now while I was working on other projects.
Now I'm back slowly working on the bike. When I try to start it, fuel leaks from the middle portion of left exhaust. Pulled spark plugs on the left side out and the one closer to the back of the bike (is that cyl 4?) Looks wet.

So I rebuilt the carbs again with new floats all honda parts. Still had some of the same issues... fuel out of the exhaust and wet plugs. Turned out one of my coils was also dead. I replaced ignition system with the dyna coils, wires, and electronic ignition. I believe the original problem was the 1st carb rebuild was set wrong somewhere and when I did the 2nd I paid more attention to details. The ignition system was probably my original power problem.
