hi, sounds like a stuck float in your carb. Try tapping the carb briskly! sounds like gas is slowly dripping in the bowl overnight and you burn it the next day. I would take the bowl off and see how much gas pours out. It should come out like a light stream of pee. Could be cloged fuel filter or a gumed up or broken float, carb rebuild kits are cheap.
Good Luck!

Rebuilt carb on yam 350 warrior now gas is running out of carb and overflow

Woopsies, something amok with the float/inlet valve area.

Typically you get a tiny piece of gas line material that drops into the inlet valve, after a rebuild...

But recheck the float system.

Stuck throttle, wont turn...Frozen ? been siting 1992 350 DR

Disconnect your throttle cables from your carb. See if you can manually move the drum on the right hand side of the carb. If it moves freely and springs back, the carb is good. Twist the grip and see what happens. Pull the two screws out of the casing that mounts to your handle bars and disconnect your cables. try twisting the grip. If the grip is good then VIOLA! You have isolated the problem. I recommend bathing the cables in WD-40. I have a 92 DR as well and that definitely made a difference for me. At this point it wouldn't hurt to remove your twist grip and clean it all out. You are at that point anyhow, may as well make it worth the mother of disassembling it all. Good luck!

My '92 drs 350 has a leaky fuel petcock. it is a vacuum assist type. What would happen if I override the vacuum assist by just installing a solid gasket in place of the diaphram assembly? Flooding, leaking...

It may be ok , but many bikes flood when sitting over night and fill the sump with fuel. if the carb float doesnt quite seal.
Not sure about epa , I think it shouldnt be a problem unless carb overflows and drips on the ground, during the inspection.

I bought a basket case 91 suzuki dr350 and i cant figure out how to install the carb, I dont know what lines go where, any information would help. thanks

There should only be one main fuel line, from the tap to the carby, the rest are just overflow, and vent hose. If you have a vacume operated fuel tap, then it will be a smaller hose, from the tap, to a vacume pick up point somewhere, mabey on the inlet manifold.

2003 WR250 F - eng. won't idle down and carb starts to overflow

Hi Jwelden,
Have you checked the float level in the float chamber?
I guess you may have to reset the float pin adjustment, its allowing more gas to pass through thn required and thus the overflow!
Not bad too, when you are working on the float assembly take the opportunity to blow out the fuel line from petcock to the carburator via the seat for the float pin,any foreign particals there would stop the float pin to seal up and thus overflow.
Fit in an inline fuel filter , this will help keep out the dirt or whatever.
Hope this helps.
