Default This is the result

AF on 8000 rpm is 12.5. Also "good" on other rpm's.

No hesitation, but a small "thing " around 3000 rpm (too fat) when bottoming at 2000 (which I seldom do. Acc. pump causing this?).

Idle fine.

Idle jet: .050 screws out by 1/2 turn.

Acc. jet: 45. Nuts all the way out. (Or 3/4, if you take off what I have cut off the threads)

Emulsion tube: F11

Main choke 40,5mm

Main jet: 155

Air corr. jet: 170

This is with a 308 deg. .613 lift solid roller 347 with 40 deg max ignition, Mallory Al6 and no RPM limit (runs out of power at around 8200), K&N air filters (large), medium stacks.

May be refined some, but really happy. Only a rolling- road trip is missing....

Thanks for all tip & trick learnt by people at Club Cobra forums.
