Another 660 jetting question
 

660 jetted with 148/146 jets and 3 turns out on the air mixture screw. Runs great at 5000ft +or- . Im am going slow and rock crawling, stream crossing at 9000ft so adjusting the mains didn't help. Been trying to get it to run a 9000ft with no luck. I've dropped the mains no luck put them back. I think I need to adjust the pilot jet but can't find any information on what size to go to. Help. To hot to play at the dunes
