Gas pouring out Gl1000 exhaust.

Post by YourJere »



I thought I incorrectly set my floats since thats the only thing that could let gas through. I swapped things out and looked at it and just make sure it was good, and it still pours out fuel and its the rear right carb. I did a bit more googling and I couldnt find crap til I looked here https://www.goldwingowners.com/forums/1 ... haust.html
and there a guy says his plenum gasket vacuumed gas through and I guess IM gonna order a new one because this is my 4-5th time taking the carbs off for this exact issue.
Has anyone here ever had that issue?

I had a bad float set that would jam open, had to replace the float and needle, plus a good cleaning of the seat.

I don't think thats the issue with mine, when I say it pours gas, it really does pour, if I ran it for over 5 minutes id probably have a few cups of gasoline.
It could be so I plan to take it off again and swap alllll the stuff in the bad carb to one on the left and see if the left starts leaking then if thats the issue, I will swap back the float itself to see if the float is bad or if its the needle valve. With the needle valve luckily Ill just take an old one I took out the carb and the seat and put those in there and hope it fixes it.

The carb that floods is the #3 carb, and I read all the gas goes to carb #3 first then it supplies the other carbs with fuel? IM not sure.
Before I swap the float though Im gonna submerge it under water and see if bubbles come up or something, just check that kinda crap.
Its starting to piss me off lol

I dont want to spend money if i dont have to either.

To check the float, just put in in a jar of gasoline overnight to see if it turns into a "sink" instead of a float.

I switched out the the bad #3 carbs float and needle / seat with one on the left, put the carbs back on, and now it backfires out the air intake/plenum and thenn catches on fire. And also the carb now makes a rattling noise it sounds like one of those pistons bouncing up and down.
Id tell you if swapping the floats made a difference but it doesn't run good enough for me to tell. I was worried my timing is off or something but this only happened after messing with 2 carbs.
Is there supposed to be gas in the plenum?

I took apart the carbs, and Im missing 2 carb to plenum fuel seals.
Also lucky me I realized I can blow through those air holes to see if the needle valve is working, and Im pretty sure my floats are very wrongly adjusted so tomorrow, Ill order those fuel seals, and buy a measurement tool at ace hardware in mm so I can set the floats correctly and hopefully a week from now I dont have issues that are insanely hard to figure out.
