15hp Briggs carb flooding question

[lhemrick]

I have a 15hp Briggs in a Sabre by John Deere. I have got it running but it seems to be flooding. I'm a Vintage Motorcycle guy so I just have to ask where do I need to start to correct the problem?

You could try cleaning carb, make sure float is good, float valve, and seat are clean.
You can also replace float valve and seat if needed.
Also check oil for gas in it.

Thanks! I haven't been inside the carb myself but my son has and said it was clean. Is there a float height adjustment?

 

[Mikel1]

If float valve doesn't make a right seal to seat gas continues coming in. A damaged float will also cause fuel to keep entering.
Probably not but engine #'s would help.

Had a B&S with a carb flooding condition from time to time and it turned out to be the inlet needle.

Old one looked good.

Very deceiving.

Replace inlet needle whenever anything to do with flooding and leaking occurs.

When my son brought it home the crankcase was full of gas.

that would be the needle and seat and or float not working properly.
does it have a electric fuel solenoid on it?
if so it maybe defective
(a lot of people install a in-line fuel shut off valve as a backup)

I will have to check tomorrow. I'm on duty at the fire station today.

Electric fuel solenoid will not cause flooding.

That is the inlet needle and seats job.

A rubber tipped one is the best and most often see, so the seats don't need replacing as they don't wear.

Electric fuel solenoid often cause no starting because they fail to open when turned on and don't allow the gas to enter the carburetor.

Electric fuel solenoid are actually a safety feature so when it's stored in your garage the fuel line is automatically closed off, without these the flooding could cause a fire.

Many garage fires are caused by people leaving the fuel on, then moving things around which can bump open the inlet needle and flooding occurring when the engine is not running.

The industry is trying to save ourselves from ourselves. ha ha ha

Whether or not it has a carb solenoid has nothing to do with whether or not it is flooding. An inline shut off valve is a must for these engines and use it when the engine is not running - every time.
