Hey there BuddyLee, just thot I'd share what finally fixed mine. I have the same quad and had the same issues.
Replaced regulator-didnt fix it
Adjusted valves-no better
Cleaned carb-no difference
Then when I was putting the carb back on I noticed a small hole in the intake tube between the carb and the head🤨(looks like it got too hot once and melted a little) so I got some high heat gasket maker and smeared the hole shut and perfect, throttles all the way up, lots of power and running sweet!
