It has nothing to do with the adjustments, what is going on is your float is stuck in the carb , you will have to take the float bowl off , float is sticking than you will have to try and clean the needle and seat valve.

SOURCE: my WD seems to flood when it is being driven,

It sounds like during the rebuild the float level some how was changed to a higher setting. There is a tab on the float that needs to be bent in order to change when the float valve actually closes. Seems your float valve adjustment is allowing the carb fuel level to be too high which will create the exact symptom that you described.
If the level is fine then there can be a small piece of debris in the float valve seat.
Also.. if the float itself has filled with fuel it can be too heavy to float and cause the float level position to remain low even when the carb is full not allowing the fuel supply to be shut off. If the new o-ring for the float valve was cut during installation it can also cause your current symptom.
At this point I just think that a float level adjustment is all that should be required.
with the float bowl screws loose the bowl should never overflow in a static condition. If it does the float level adjustment is off.

Thanks for using FixYa.

If you're not having any electrical issues then Check the governor.

SOURCE: 50cc moped runs great until full throttle then boggs down-does not do it at 1/2 or 3/4 throttle

Check for good fuel flow to carburator. If so have a qualified technician look in the carb for debris blocking the main jet. this is very common when the vehicle sits for an extended period of time.

I have a Craftsman Snow Thrower model # 247.881731. At the end of last year I drained the gas as recommended in the manual, this year I filled it with fresh gas and it now has a problem starting. I pu


Draining the gas from the tank doesn't drain the float bowl in the carburetor. It still had last year's gas in it. Gas will start to turn to varnish if left sitting 6 to 12 months. You'll probably have to remove the carburetor, disassemble it and clean it out with Gumout carb cleaner or some similar product.
When you get it running and the snow's over and done with, put some Stabil in the gas tank to prevent the gas from converting to varnish and then start it up and run it until that stabilized gas is through the carburetor and into the engine. You can leave it with the treated gas in the tank.

It's flooded like you say.
If it's really flooded, you'll have to remove plugs and dry them off.
Install them.
Now when you crank engine, hold gas pedal to floor.
That will stop gas from spraying into engine.
You need to get the gas out of the engine for it to start.
Crank for 20-30 seconds with pedal to floor. Do this 3 times waiting 2-3 minutes inbetween cranks.
The starter needs to cool down.
Then after that start normally and see if it will start.
Remember if it will not start after 2 attempts, then the possiblity of it flooding is there and you'll have to clear out the gas by holding the pedal to the floor again.

Wont run hard start, run for five min or less then wont start


Many chainsaws have the fuel tank mounted very close to the engine cylinder. In the process of filling the tank over and over a lot of mixed gas is spilled and some of it runs down on the cylinder head. Being mixed gas and having oil in it, it leaves an oily residue. This oil will seem to collect a massive amount of sawdust over time. The sawdust coating the cylinder causes it not to cool down really well and the increased heat can cause the fuel in the tank to boil if it's bad enough. If the vent in the fuel cap is plugged and the gas in the tank gets hot it tends to pressurize the gas tank. This can cause the saw to flood out or load up.

Change the gas cap or clean out the vent filter. If you can get to the cylinder clean all excess oily sawdust from the cooling fins.
If you get the saw running your probably should readjust the mixture settings.

You need to set the mixtures for the carburetor. You will find a Low and High adjustment screw. At idle turn the screw in or clockwise until the rps starts to decrease. Then start turning it out till you hit max idle rpms. Turn screw back in a quarter to half turn and it should be idling smoothly. Be careful here and get someone to hold saw if necessary but hold in throttle to full speed and do the same with high adjustment screw. turn it in till rpm starts to drop then back it out until you get to max rpm and it won't go any higher then turn it back in a half a turn.

Check the vent on the gas tank. Open the lid when it is hot and see if alot of pressure escapes, if so the furl tank vent is plugged and building up pressure to flood the engine.
