Ask Your Own Small Engine Question

Did you replace the fuel filter between tank and carburetor, or does it have one? If it does NOT have a filter, the new carburetor may have water in it from the fuel tank. Need to drain the carburetor!

ok when i check for water fuel came out i pulled the vent pipe from the valve cover it would run but it was blow feul and oil mixture out to hole when it plugged it back in it quit running

Your crankcase is filled with gas and oil! You need to change the oil, the old carburetor has let gas enter the crankcase through the vent hose.

what is the best oil for it

I still use a straight 30wt. , the brand really does not matter. Needs to be a detergent oil, do not use Non-detergent

ok thanks

That is why you get the white smoke, and is fouling out he spark plug, you may also want to clean/replace the spark plug.
