Wow...thanks a million for taking the time to post the photo and instructions for me! Please help me with the following if you don't mind!
It looks like I have to remove the carb to gain access to the A/F screw?
Yes and flip it upside down. I loosen both end clamps of the carb and the clamp for the boot connecting to the airbox. I can twist mine around without removing anything except the big vacuum line that plugs for the needle jet diaghram.
I thought 2 turns out was the way it is set up at the factory?
Don't know. Mine did the same and when I adjusted, it was screwed all the way in.
Turning it out makes it richer or leaner?
I ride my Rhino (BRP CDI) in Rocky Point. What jets should I have in it or are the stockers okay?
Same as Phoenix. You shouldn't be much different just with the tip but before you remove the carb, do a high speed run, full throttle and immediately shut it down and check the plug. The CDI also let's it rev higher which may require a richer main.
What jet is located to the right of the main jet in your photo?
I think it's called the power jet but no one ever does anything with it.
Should I put a breather filter on the trans vent while I am at it? Where is it located and where do I get one?
I think your talking about the CVT filter and yes, it's a good idea. The outlet is right behind the driver seat. Check rhinocrap.com and see if they carry them or call them.
Make sure you don't drill too deep when removing the plug. You just want to get a screw in for a handle to remove the plug.
