Unexplainable carb overflow pissing like crazy - Help?

[maggot]

Well, I was having trouble with my tank breather line. So I took the tank off, ran through all my lines, diagnosed the problem, replaced my breather line, ran the fuel through to check, was happy with it, reassembled, checked the lines all again, turned my fuel tap on, no leaks, no problems.
Started the bike up, ran it up and down the drive a few times in first, ran my revs through to check it was revving right, a few more laps of the drive, parked it up, and revved through again. Then I looked down, and I had a puddle at my feet (from the bike, not me ). So I turned the engine off, and the fuel tap off, and dropped down and checked all the lines, they were all secure with no leaks. So I turned the fuel back on, and I noticed the overflow at the bottom of the carb was steadily leaking gas.
I don't get why.

Any suggestions, explanations, advice?
This wasn't happening before I stripped it, and I didn't touch the carb at all, except to remove the fuel line from it.

I'm seriously confused.

The bike is a 2-stroke, Suzuki RGV150.

Cheers in advance

"Totally unexplainable"?
I think not.
The usual cause of carb(s) overflowing is either something worngA with the float (like a hole, or the arm/pivot sticking, or crud under the needle, so it doesn't shut off properly.

The V-man is on to it

Give the float bowl a tap with the plastic end of a srewdriver to try and remove the crud that's causing it.

Now that you've cleaned your tank and fuel line and washed all the crap into the carb, take the carb off and clean it out too.

Another possibility is that the o ring around the needle valve body is leaking. If it is then it won't matter how well your needle valve is sealing against the seat - your carb will still overflow.

Took this guys advice and it worked, no more leak.
Thanks plenty for the advice.

I'll look at getting to the carb and cleaning it out tomorrow when I've got some old hands around to help me out.

Cheers to all.

sigh. old suzuki tanks, always rust & silt goes everywhere downstream. Filter isn't enough to stop it. Only solution is to run some sealer int he tank like POR15 or Kream. Do a search. Only think to watch for is that you don't block the tank breather with this stuff, . . . um, yeah, did read your other post.

POR15 FTW - the Kreem stuff's not as good.
