1986 husqvarna 125 radiator hose set up

Trying to figure out how the hoses connect. I've looked at the manuals I can find online they all apply to 250 and up though. The 125 had a different set up with a hose connection in the top of the cylinder and the side rather than the top and the back. Any help appreciated.

Also what type of oil should I use?

you can use atf- f in the gearbox or 30 wt oil. in the motor, use good quality 2 stroke at 40:1. I use the castor 727 as it smells good

Thanks for the pictures. I'm still a bit confused though by that last one. Do you have anymore?Do I have mine done wrong?

Thank you very much.
