Why does my carburetor keeps flooding?

The most common cause of flooding is dirt in the needle & seat. What happens often is you clean your carburetor, then start the engine. Dirt from a dirty gas tank, or in the fuel line rushes up and into the carburetor. The fuel pump is another possibility.

Why is my Walbro carburetor not working properly?

You may also have an air leak at the base of the carb. The throttle butterfly could be damaged or worn out. Float needle is bad or has crap stuck in it, or the float lever setting may be too high, or the float diaphragm is bad. This is perfectly normal for carbs NOT equipped with a “check valve” highspeed jet.

Which is the best tune for a Walbro carburetor?

All Walbro carbs will run in any position, but they tune “best” as a side draft carb meaning the airflow intake is horizontal. The down draft position tends to run a little rich at idle, and the updraft tends to run a little lean at idle although it’s easily tuned regardless. Your ENGINE will determine which pulse inlet type you need.
