It may be simply that your fuel level is too high. There is a bleed hole on the left side of the main carb body, just above the bottom union nut to take care of any over fueling. There are two or three different heights of union nuts and an M20 should have the shortest one. Usually the problem will go away once the engine is running. You can't alter the height of the float but you can alter the height of the bowl with an extra washer. Ron

Thanks Ron I'll have a look at that tomorrow night.
