uneven Weber fueling
Hi. From the good advice from this forum I have re-jetted my Weber. The car seems to drive okay except for a slight stumble at 3000-3500rpm. When I look down the Weber's barrels, I noticed the front barrel starts getting fuel droplets (from mains) at 3000rpm and the back barrel around 3500rpm. At higher rpm the front Weber barrel seems to deliver more fuel (this is a visual observation) compared to the back. I'm guessing this is why it stumbles - front rotor is seeing more fuel than the rear rotor.
Note: The Weber does tilt slightly forward toward the front rotor.
Is this a problem? How can I even the fuel delivery?
Thanks.

it could be all kinds of things, exhaust design, engine health, bent throttle shaft, the venturi to the carb body can leak vacuum, the jets and e tubes can be dirty or not seating right in the carb body, etc etc
in theory tilting the carb a little would change the float level for the front and rear rotors, but so would hitting the gas or turning...
