Carb Tuning

Cruising, it still runs great, since these have nothing to do with fuel mixture at speed.

Actually your engine will spend most of it's crusing time on the idle & transition circuits and very little on the mains.

FWIW, you need to get the timing right before you mess with the carb. The XE268 cam will want somewhere around 14-16 degrees BTDC for intial timing.
