If you put in too much yes or...if the timing is not correct it will do that as well.
squirt a little gas in the carb.
the carb needs to be rebuilt or cleaned. old gas clogged the jets
I would suggest you get a good crab cleaner and soak the carb in it.If that does not clean up your problem you will have to take the crab apart and clean it with cleaner and compressed air.
its normal to hear air being sucked in to carb with air cleaner off is it a sucking whistleing sound if so could be an bad vacum hose
No
If yours is self propelled and has a drive clutch you can let off of the drive power. What is happening is your snowblower is trying to eat more snow than it can in a reasonable amount of time. If you are not under an excessive load, its usually a blockage in the carb or old fuel. try new gas from the gas station, replace your spark plug, if this doesn't work you may need to clean the carb.
Remove the air filter, and while the engine is running spray the cleaner into the carb directly, being careful not to stall.
It means the carburetor has 2 accelerator pumps instead of one, as is normal.
No fuel in tank; clogged line at/in the fuel tank; clogged fuel filter; carburetor needle valve is closed, fuel float stuck closed. Disconnect fuel line at carb, if you have fuel there, the problem is at the needle valve or float; if no fuel. the problem liies between the carb and the tank, next methodical check would be the fuel filter, etc.
From my experience with small engines, first check for all safety releases up near the handle, - make sure the plug isnot being grounded by a safety devise. A common problem is that fuel is left in the tank and carb over a season and a shellac can form inside the carb as the fuel sits or evaporates. If you can, drain all fuel from carb bowl, and tank, Assuming the carb is cloged, try spraying starting fluid directly into the carb bowl possibly through the fuel line. Let it sit for a while to see if the volitile vapors will help open it up. You can then Mix new fuel oil, add some treatment such as Stabilze, to prevent and remove any remaining shellac, replace plugs and it should start. If not, maybe take it to small engine repair place
Well, no. But its normal for the float in the carb to get get stuck and cause the gas to overflow through the overflow tube.
too much fuel is being pushed into the cylinder from the carb
