Carburetor rebuild

Hi everyone. I really hate to make my first post as a question about whats wrong with my ATV, but I'm having a conundrum.

My Dads Prairie 300 has been sitting for the last few years and he finally decided to sell it to a friend of mine. Trust me the carb is clean and flowing air or fuel thru all the right places. There is nothing clogged. The motor starts on choke but if I turn off the choke it will die. It won't idle without me holding the throttle open, and to start it w/o choke I have to hold throttle WFO. All of this makes me think the pilot jet.

Dad ordered a new pilot kit. It came with a new jet, a spring, a washer and an o-ring. Going by the exploded diagram I should have the o-ring go into the carb body first then the washer, then the spring then the jet set at 2 turns out..

The way I see it with the o-ring going in first, it would block the fuel from being drawn up thru the starter jet and into the intake behind the throttle valve.

So I think the spring needs to go in first then the washer, o-ring then jet.

Please point me in the right direction, if I can get this thing running then I can get a riding buddy again.
