Hello I have 2F. I need to know what is this part in the image. It leaks some gung, but that's it.

Crank case vent, PCV valve.

Do I need to do anything or leave it as it is

Normally that has a hose connected to the air intake, to recirculate gases into the engine.

Good point; what I posted is from the 1981 factory emissions manual.

 

[jumans]

Mine is 1983.

How about a picture of your air cleaner and one from the left side of the carburetor?

Mine is 1983.

Then the 1981 emissions manual pages I posted are the right ones for a U.S.A.-spec 2F; yours may be different. On mine, there is a hose that goes from the PCV valve, around the back of the air cleaner, that connects to a metal tube on the driver's side of the engine. This metal tube bolts on to a fitting on the intake manifold.

Nice paper clip Lee.

Nice paper clip Lee.

My accelerator pump has not worked for a long time; I did the paper clip test way back when, and never took it off. I'm used to it running that way. Some day I will rebuild it - pretty sure I have the parts packed away in the shop somewhere.

Anyway you go with this, you need a new grommet for the PCV valve. The part number is 90480-18180.

THis is my setup.

Since you don't have the stock carb or air cleaner, I would put a T-fitting in the line going from the back of your valve cover and the bottom of the air cleaner. Then run a hose up from the PCV valve to the T-fitting.

You mean put a T-junction on this hose.

Yes, I thought there was already a splice fitting here, I didn't realize it was a tie.
