Correct that there are no adjustments, but try cleaning the carb jets first, as many times a small amount of debris in the fuel can cause a performance problem. A replacement carb will be close to $200, and NO carbs will be adjustable. A gasket kit is available if you need. Contact your local Briggs dealer to procure the part.

Try cleaning the jets first.
Fuel Starvation - Float Bowl Carburetor
1) remove air filter assembly
*be cautious of tearing the mounting gasket. If it does tear, you HAVE to replace it. It is part of the priming system
2) remove the float bowl fastener. This is the main jet
3) carefully remove the float bowl, the rubber o-ring/gasket will not be able to be used if it is removed, you WILL have to replace it
4) using a spray 'carb cleaner'
spray up thru the center of the carburetor
spray and clean the main jet with cleaner and 'tag' wire
(tag wire is very thin, and can be used to clean the hole in the center of the main jet)
5) clean any debris from inside the bowl or carb body
6) re-install bowl and center bolt, air filter assembly

*if you need gaskets, your Briggs dealer can supply. The kit is cheaper than individual gaskets, and all the parts needed to finish the above repair are in the kit.

Tip

Float valve overflowing on a motorcycle


My Yamaha wr250 was leaking fuel out of the overflow badly. I cleaned the seat, changed the valved, adjusted the level. Nothing worked. In the end, it turned out the seat was damaged due to age. Yamaha did not sell a new seat for it, you have to buy a new carburetor. Here is a tip that is easy to do to resolve it provided you have already replaced the float valve, adjusted the float level, and cleaned the carb.

Items needed:
a small tube of lapping (valvegrinding) compound(Available at your local auto store)
1 can carburetor cleaning fluid.
About 5 Q-tips (If your float valve seat hole is bigger than a normal Qtip, you can purchase oversize ones at any drug store)
High speed drill

remove the carburetor, bottom bowl, float, and valve.
Put one Q-tip at a time in the drill
Apply a dab of lapping compound to the end of the tip(about twice the size of a b.b.
Stick it in the float valve seat and letter rip for about 10 seconds. The Q-tip will take on the shape of the float seat and lightly polish the seat smooth again. You might want to do this a couple of times the first time to ensure it takes.
Once you are satisfied that all scars are removed, take a can of carburetor fluid and spray out the seat. Ensure that all the lapping compound has been removed.
Put the carb back on. Try out the bike and see if you can get it to leak. If it does, repeat the process. I had to do it about 5 times to get mine to completely stop.
Final Note. This tip is provided for people that have already replaced the float valve, adjusted the float level, and cleaned the carb. If you cannot purchase another seat for your carburetor, without buying a new carb. this beats that hands down, but I strongly suggest you do the first three steps first. Anything goes wrong, your not out anything anyway.
Ride hard, or stay home.

1996 750 katana suzuki how to set floats?


- Now days some carburetors are produced which are fixed and no adjustment is provided.The float is made up of whole plastic like material.
Some floats have the copper/metal notch for the adjustment of fuel level.
- Take the carburetor assembly out.
- Remove the fuel bowls.
- Place the carburetor assembly with the floats upward towards yourself.
- Float level gauge and active data list (taken from the workshop manual) is required to carry out the adjustment. But you can simply adjust the float level correctly without any gauge.
- Hold the carburetor assembly at your eye level in such a way that the carburetor No. 1 is in front of you. Behind is No. 2 carburetor, then behind is No. 3 and then the No. 4. Or we can say that the carburetor No. 1 hides the carburetors 2, 3, and 4.
- Examine carefully the floats of all the individual carburetors be parallel to the surface of the carburetor where the float bowl face is seated and tightened.
- Adjust the float level by bending the float notch towards the needle valve (to decrease the float level and to raise the float) or away from the needle valve to increase the float level (to lower the float).

Briggs and straton 205412-0187e1 runs on full choke only rebuilt carburetor due to surging now it only runs on full choke


This engine came with 2 different carbs. Walbro and Nikki. The Nikki carb has a very fussy float plate! I fight them often! Usually there is a problem with the odd gasket that lifts the flat plastic plate and causes a very low fuel float level in the carb so the only way it stay running is to have the choke on. The main fuel jet on both carbs is up inside the threaded area of the bowl nut. When the main fuel jet clogs...and it only takes a speck of something you also get the symptom of having to use the choke to keep it running.

http://www.partstree.com/parts/dispdiagimg.php?src=r&ilFN=D%3A%5CEMPARTweb_52%5CCatalog+Data%5CEMP_IMG%5CBRG%5Cimages%5C6359%5C0004.TIF&ilSC=10&ilIV=0&ilBR=0&ilIF=G&ilRE=8&ilSH=0&ilEG=0&ilRO=0&ilSC=24

Main fuel jet is item 117 Nikki or Screwed into item 142 Walbro of the of the above link depending on which carb you have.
The plate I am talking about on the Nikki carb is item 135. The fussy gasket is 137A.

THE threaded area is where all the main fuel supply is drawn from the float bowl. All that must be free of obstructions. Until this is clear and orifices / jets are not obstructed; your going to be running on choke....

Thanks for choosing FixYa,

Its a briiggs and stratton 16.5 hp model #313777 0112-E1. I'm gettin gas in my oil and am pretty sure float is sunk and it won't start at the moment. The carb bowl spins clockwise and counterclockwise but...


You need to determine if you have a Nikki or Walbro carb. The Nikki bowl is held on by two phillips head screws and the Walbro bowl is secured by either a single bowl nut or a anti-backfire soleniod (two wires going to it). Your problem is probably the seat in the carburetor. We see very few float problems since most of them are plastic.

If you have a Walbro with the anti-backfire solenoid you will need to get a slim 1/2 open end wrenc the access the "flats" on the solenoid to unscrew it.

The brass seat is replaceable in the Walbro along with the needle. If it's a Nikki, you may need to replace the carburetor.

Hope this helps
