What in the world? The trash? That’s how u file Polaris Phoenix manuals? Lol
Well that's how my mail server sorted it for me - I had to tell the server it was not trash
How in the world would the fuel screw be installed if there isn’t a provision for it? I would have to drill and tap it?
The fuel screw is depicted on the side when in fact it goes in the hole in the in the well next to the float bowl on the bottom of the carb.
Now maybe the mail server was right and the manual is garbage - in one pic they clearly show the air screw in the side of the carb
But the pic is of the Mikuni VM carb used on earlier models
Years of Phoenix through 2014 spec having a Keihin VM22 carb
In 2015 the spec changed to a Keihin PTG22
If you notice in the pic, the carb has a round float bowl and the one you video'ed has a square or rectangular bowl
Now on page 4.12, the manual shows how to set the float level depicting the Keihin carb, but while the text describes tilting the carb to get the float tang resting on the float needle pin, the pic is oriented incorrectly
On page 4.13 they describe testing the float needle seal - again illustrating the Mikuni carb
Finally on page 4.14 the manual illustrates checking the fuel level this time depicting a Mikuni BST CV carb
The manual is fraught with errors and incorrect representations
You (the mechanic) is expected to know what you are working on and where the parts go regardless of the pics in the manual.
Since you paid for it, you should complain - all in all, there is a majority of correct information, but the elementary school editors and proof readers who never even saw an ATV have used pics and text from previous manuals to assemble the current revision. This is what you get when you mandate a 'minimum wage' for inexperienced employees. I worked for 25 years in a factory to earn $16 per hour and I nearly ran the place, now new hires are being paid nearly the same wage and they can do without instruction is finding the rest room.
Get the screw set and put the fuel screw together correctly (place the spring on the screw, then the washer and then the o-ring and insert into the hole - screw in till it touches (might be able to see the tip of screw or feel it in the throat of the carb on the engine side of the butterfly valve))and back it out the prescribed
initial setting - run the engine for about 20 minutes (not idling - riding) - when fully warm adjust the fuel screw for the smoothest idle and you are done.
