So the hesitation during acceleration showed up again. Dadgum.

Decided to gasket-ize the new adapter. Right in the middle of the two adapter pieces. Just in case. While I had the carb off I inspected the throttle blades. They were sticky before I rebuilt it. Certainly not sticky. Double guessing myself is all. But, found that the throttle cam moved a wee bit before the accelerator pump moved.

Hmm.

Sure enough, the throttle blades would open about 1/16th before the accelerator pump would engage. "Gee" I said, all by myself in the garage. "Wouldn't that mess with the air/fuel mixture?" I'm sure the old-timers reading this are saying 'saw it right off'.

Long story short, adjusted the "throttle rod" to remove all play in the throttle cam. Hesitation at acceleration gone.
