I reset the throttle and mixture screws to no avail. It will run perfect, then the idle just falls out of it. When I pulled into my driveway the throttle pulsed and wanted to quit. I floored it and it sorted itself out.

The hard part is everything works perfect, set properly, then for now reason, the idle just crashes.

Like I said previously, its a 1 in 5 chance it happens, not consistent.
