Yamaha Jog cg50 carb connections

[piccolo]

Hi,

My scooter is a Yamaha Jog cg50 from -87 or -88.

I got a new carb but not quite sure where to connect everything.

Number 1 and 6 is for cooling liquid and I have air cooling so I have covered them with a tube like this:

- Number 2 is float ventilation, what do I do with that?

These two hoses are coming from fuel tank:

I have connected the big one to fuel/gasoline connection.
- And the smaller one to number 4, which says oil/vacuum connection, is this right?

Then finally we have these two hoses coming from what I believe is the oilpump:

Larger tube I connected with oiltank.
- Where do I connect the smaller one (the one bent 90 degrees at the end)?

Best regards,
Piccolo

The smaller oil line connects to number five.
As you have removed the oil from the pump line. You will now need to bleed it or the pump won't work.
