To remove the Tors you need to get the caps for the tops of the carbs and the idle screws... There are alot of things that can make it bog. sence it is new to you, i would pull the carbs and clean them and see what they have for jets in there.. I dont know about where you live but today was worm for me and the weather can make a difference in how it runs if it was jetted for colder weather..
