SOURCE: gas leaking through hole in carb into the air filter

It could be a bad gasket or o-ring that needs to be replaced. Is it possible something vibrated loose and you're missing a part? You can probably get a carb rebuild kit that will provide many of the gaskets, etc. you would need to repair it unless there is some physical damage to the carb itself.
Also check the fuel line carefully to be sure that is not the source of a leak that is running along the body of the carb and dripping from somewhere else....

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.

SOURCE: Carb leakes gas out overflow

It doesn't take much to hang the float valve open. The smallest speck of dirt or debris will cause the float valve to not shut the flow of gasoline off. After sitting for that length of time, the carburetor needs to be completely disassembled and cleaned. Use an automotive carburetor cleaner (but do not put any plastic or rubber parts in the carb cleaning solution as they will be eaten up). While you've got the carb apart, inspect the float valve. Replace it if there's a groove worn into the tapered seat. Installing an in-line fuel filter may help, too.

I put a mixture of oil gas in my 621 R/621 toro snowblower?

Hi Jerome:
Shouldn't be too bad.
You could disconnect the fuel line at the carb and drain the tank.
Drain and flush the carb. Reconnect the fuel line and fill with fresh gas.
If it won't start, pull the spark plug and clean/dry it with a propane torch, or replace it.
Odds are it will be fine.

The tecumseh carburetor on my mtd snowblower is leaking gas from the throttle hole on the side that is facing away from the engine . the carb is new and so are gasket i cant stop the gas leak

Gas is coming out of the area where the air filter would go IF a snowblower had a filter....That happens when the Needle valve is stuck open for some reason. Either the Float that closes the valve has a leak and sink in the gas or the needle is slightly rusted in the carb in the open position. you need to take the bowl off the carb and see if you can easy lift the Float and see the needle valve moving up and down. A;so see if there is gas in the float. There shouldn't be

I have a toro snowblower. i cannot pull the pull cord. it feels like it is stuck.

Pull your spark plug out and see if the cord will pull out, if it does than that means your cylinder is full of gas which is a result of ethanol in the gas causing the needle valve to leak causing fuel to siphon from tank to cylinder, pull your carb off and put a carb kit in and you will be blowing snow in no time,if this isnt the problem then enjine may be seized up and its time to replace blower. Good Luck!

6hp toro snowblower. cleaned carb, reinstalled all parts, engine ran for aprox. 10-15 seconds then shuts down. appears to be straving for fuel. push primer button and it will start up and then shut down

The diaphram in the carb is not working or there is an air leak somewhere in the intake or the float may not be working or the needle inside the carb may not be working or it's sticking.
