If I'm not mistaken the choke on the FCR carbs richens the starting circuit. The hot start would lean the carb, have you checked the condition of the hot start plunger? I have a thumb lever for the hot start mounted on the handle bars and sometimes the plunger gums up and is hard to operate.
What does "It Will Only Run Above Fast Tick Over" mean?

I found out that the worn plastic threads on the hot start insert into the carb were allowing more air into the carb and causing the problem. Replacing the hot start plastic/threaded piece solved my problem. I don't know what style of hot start you have on your 02 426, but you might want to check and maybe replace that piece.
Buy and new WR 450 and call it a day!
