What do the plugs look like? I think you're running rich. If you give the throttle a quick goose the accelerator pump will squirt fuel. If this makes the engine bog or die, it's not lean.

Your idle jet seems way too big, especially for a low compression motor. Try a 53 or a 55.

Tuning Dellortos is a complex process that even Jensen never got right. Do you have the Des Hammill book?

Balancing is required using a 4 tube manometer.
