I agree,

I am not the one tuning the carbs. But I find it hard to believe that I had a leak in the first place when I took it to him. He rebuilt the motor and the intake gasket looked good. He then reassembled the motor and we are at the same problem.

I was thinking and tell me if you think this will work.

Remove the carbs, then make an adaptor of some sort to connect to the intake opening of the carb. Connect this adapotor to a vacuum and measure the suction. making sure the intake valve is closed.

continue to do this across all ports of the carb make sure intake valves are close with each cylinder test.

I am hoping that this test will assure that there are no vacuum leaks.

What do you think?
