I pulled my 66 912 out of long term storage recently cleaned her up a bit. checked oil and changed battery. cleaned up points, cap, and rotor and she started up and ran pretty good.

But...

on the shakedown cruise i noticed significant hesitation on partial throttle but good running and acceleration when it is more open.

sounds like a carb / jetting issue right?
but, i remember having this problem before with different carburators.
could it be distributor / timing?

i'm running dual weber 40s (previous were dellorto 45s.
1750 big bore kit.
050 distributor
bursch exhaust.

where would you go next?
can you point me to any good writeups here on carb tuning and timing?

Thanks in advance for the help!
