Hi, here we go again, I'm going to respond to all of the questions/suggestions listed above.
the clutch does not slip. The sync tool has been used successfully. The vacuum gauge holds steady at 14.75.
How do I set the accelerator pumps a little richer?
There is also a piston and spring assembly next to the tower where the jet is installed. How is that spring adjusted to modify the operation of the carburetor?
I used ETHER to check for vacuum leaks; we tested around the three intake connections (intake to engine, carburetor to intake, sides of carbs for butterfly valve shafts being loose), with no issues at all.
Timing is interesting. We set the timing up at about 8 degrees and found out it runs best at about 12 degrees. Then not using the timing light we rotated the carb counter-clockwise and then clockwise looking for what the engine liked the best and set it there; approximately 12-14 degrees.
i ran the carbs from idle to full throttle and they both respond the same way at the same time. Near full throttle we get a popping sound, no longer a steady roar. the carbs respond immediately and without hesitation.
I installed a used 261 cam and so am going to run a compression test next to make sure I've got proper valve operation. If It does not have good compression I'm taking the used cam out and will install a new 261 cam.
Thanks, for all the help guys,
Ted
