2001 Polaris Sportsman 90 Bogging

2 stroke Sportman 90 --- This past weekend my daughter rolled the atv. There was no damage to it and it fired right up after the roll. It was ridden off & on all day with no problems. At the end of the day when she would give it throttle it was fine till it felt like the clutch was engaging (a load put on the engine) & it bog down. It starts and idles fine. Brought it home and blew out all the lines and took apart the carb and blew out that also. Put it all back together and it still bogged when the clutch started to engage.

I did some other things and came back to it about a hour later to run the fuel out of the carb to put it away. I hit the throttle and it took off with no problems. So I rode it around for about 5 min at full throttle with no probs. So the next day I ran it again wide open for about 15-20 min and then out of the blue it bogged down. I pushed it back to the house with it idling.

Why is this doing this? Its speratic. What should I do now?

Do these have a safety switch on the throttle in case it ever breaks? It might have gotten damaged/misadjusted.
