Latest tuning done to my webers.
After installing a wider hood scoop to make more space for the air horns, I did not make a new wider scoop cover, so had again the hesitation at mid throttle. Installed a cover and the hesitation is gone.
I was shooting out black smoke on acceleration, so installed a .35 bypass and the black smoke is much reduced, so will need to go to a .50 bypass.
A slight bog came up when using the bypass, so installed a larger idle jet, .65 before, .75 now, and the bog is gone. Idle air is 120, idle screw 1 turn out.
Installing the bypass has another positive side to it.
Apparently the fuel trapped in the pump circuit drains now into the fuel bowl and so does not drip into the throats when I stop the engine and the carbs soak up heat.
No more fuel dripping since the bypass installation.
Engine runs great, no weak spot anywhere.
