Your carbs will need to be cleaned adjusted and synced, but it also sounds like you need your valves adjusted.

SOURCE: flooding out front cyl with fuel....rebuilt carbs

Theres a problem to the front carburator thus the flooding, the float pin is not sealing of the fuel supply once the bowl is full.You will have to reset the float, remove the bowl and operate the float manually( by your fingers lifting it to seal) letting the fuel to flow, if it stops thn for sure the float needs adjusting, if it doesnt stop the flow thn the pin is not sealing,you may have to replace the float pin.
Hope this helps!.

SOURCE: Carbies willn't set float level,right floods,left sets to low

I don't know if its any help but I've fixed my Honda with similar problem. It turns out I reassembled the rich carbys air cut off valve incorrectly. Have you checked yours? I'm wondering if the cut off valves somehow affect the other parts of the carbys. Mine is running sweet now.

SOURCE: Air box and crank case fuel flooding problem

Well there only one way the fuel can get into the crankcase and that's from the fuel tank. The petcock must be draining and the float needles are not stopping the fuel flow. Do you have a prime position on the petcock? If so do not run the bike in the position. Try topping the tank off with gas and letting it sit for a while and see is the gas has gone down and then check the crankcase and see if there's fuel in it again. i still say its got to be your petcock.

Could be flooding. That usually only occurs when you have excess fuel lighting off in the exhaust. I have seen it happen on cars when the timing is way off. I would pull the carb and check the float level and replace the float valve.

If you have a float style carb I believe the float has become a "sinker". Pull the float bowl off the carb and set aside. pull the float pin and also set aside. carefully remove float and needle, set needle aside. Shake the float near your ear. If you hear sloshing in the float, replace it. No? check needle and seat for wear, or since you're into the carb this far replace them. This info is based on Tecumseh carbs, but B&S or Kohler should be similar. If there are any other questions don't be afraid to ask. There is no such thing as a stupid question.

Flooding Carburetors,


Sounds like the carbs are gummed up,and the floats are stuck. The carbs will have to come off,be thoroughly cleaned,and the float levels reset,and synchronized.

Gas floods out of the exhaust manifold


Stuck float valve, letting too much fuel into the carb. Try taking the bowl off of the carb and checking to make sure that the float needle moves freely up and down. If there is evidence of gumming inside the bowl you will want to get some spray carb cleaner and clean everything in there thoroughly.

I cleaned the carbs it ran great for 10 miles and then began flooding.replaced the gross jets in float bowles. ran good but had to pull of carbs again to fix float bowl leaking now it floods so badly it...


Sounds like you need to check the needle and seat for dirt etc. or one of your floats may be sticking. A simple way to check is to connect the fuel pipe to carbs upside down with float bowl off and you will see if it is leaking or not. If that is ok then make sure that the floats are not sticking or holed. Test again by inverting the carbs again with no fuel in them and you should not be able to blow into the chamber until you turn the carbs to normal position. Hope that helps.

My lawnmower which is a TORO 6.5hp-Tecumseh engine won't start. When I pull the cord the valves start to move but on the second pull it seems to sieze up and blow some vapor out the exhaust.It ran fine...


It sounds like hydraulic lock. The carb is dumping to much fuel into cylnder. Pull the plug when it feels locked up and pull again, if it blows gas out of the plug hole you have carb problem. Maybe needle is ****, maybe float has a hole in it and is sinking causing flooding.

It does not fire all the time on rear cylender it take rear exhaust longer to heat up it dont get as hot as the front exhaust and it pop out back carb sometimes and exhaust fumes are gassy


This symptom could cover a WIDE range of problems. Lets start with simple stuff. Put new spark plugs in it. Pay attention to the ones that come out and where they came from ( is the front one white and the rear oil fouled?). Make sure your tank has nothing but fresh fuel in it. Then, check your ignition wiring for faults/ bad connections.
Hopefully that sovles your problem and you find something obvious. If not you need to methodically determine if its a ignition, fuel, or compression issue.

FUEL RUNNING OUT OF EXHAUST


If fuel is escaping through your exhaust system to the point that it is dripping it means you have a float in your carb that isn;t closing and your engine is flooding. If your mechanically inclined do a carb job. They sell kits with all of the gaskets floats needles and jets that you need, it's a moderately difficult job with lots of small parts but if you google your carb you can probably find either a you tube or similar video step by step. Otherwise it's a job for your local shop.
