On the front driver's side in front & below the 1st exhaust port, the tube that sticks out from the block....... Where does or what does that connect to ??? I have seprate air cleaners and I think it connects to the carb. balance tube, am i right ??? Why??

thanks for any input

I Believe you are refering to the tube that connects to the PCV (Positive Crankcase Ventalation) valve. It connects from the tube that sticks out from the block and connects to the PCV valve which is connected to the carburator balance tube. It's there to prevent air pressure build-up in the crankcase.

If you don't know if it is working correctly just get a new one. They are pretty cheap!
