Fustration this weekend. Tried Satuday afternoon to break in and tune the Fox 46. No luck at all. Switched carbs from a well running fox eagle 74 and this worked better, transition was acceptable but a terrible flat spot about 3/4 throttle, particularly when backing down from full throttle. Engine spit and spurted and would not recover unless I quickly choked it. Took apart three Fox EZ carbs, from an eagle 60, an eagle 74 and this 46. They should all be the same. Noticeable differences between all three carb barrels. Tried all three none worked. Seems they would just not draw fuel.

Maybe it needs more muffler pressure. Will try to move muffler pickup to header, it is currently on the expansion chamber. Perhaps pressure will be higher and sufficent nearest the engine.

Frustrated in Fayetteville,
