The throttle bore on your Monojet is smaller than one for a 292. Even with bigger jets your 292 would starve for air on the upper RPMs, and full throttle would lack in performance. The only real answer is the right Monojet, or a bigger carb, 2bbl, 4bbl. The Holley/webber (Weber DGAV) I've read doesn't work either, always on/off the throttle. Considering your location maybe tough to find something.
