    Gerry,

    With properly adjusted Solex accelerator pumps, air fuel ratio will dip very low (less than 10:1 as I recall) for a second or two.

    Gerry .... Yes, too rich will also cause a "flat spot" in the 2500-3000 area. This is the area of overlap between the idle jet and the main jet. I normally try a leaner idle jet first and that usually cures most of the flat spot.

    Accelerator jets are interesting, they not only provide a shot of fuel when the throttle is depressed, but they also provide some enrichment at higher revs.
