I dont know whats wrong with my 620. It will run for a little while and i can drive it to short distances but if i try to go over 60 it starts losing power and after that it will not let me go over 40 then 30 and eventually i have to stop and wait a little bit? also when this happens it will accelerate for about 2 seconds then stop accelerating and then it will accelerate for another 2 secs. has any body had this issue?? is so what did you do? or how can i fix the issue?

Carb not getting enough fuel, main reason. Follow adams post.  I was having cutout issues the other day, but it wasn't fuel issues :rofl:
