Hello everyone! I recently bought a 763 f series loader off my wife's family to use for my small landscaping company. I did a complete service on the machine and it seems to run and operate well. But I got in it the other day and when I went to start it with the throttle down it would start and the right side drive stick would move slightly and the machine would stall. I was trying to start it with the safety bar up. I found I can start it at about half throttle and it will start pretty well. But also when I'm using the machine the right side constantly tries to go forward more so than the left. I can let go of the stick and it will move by itself. And I can't idle down the motor before I shut it off because it will stall. Any suggestions or tips? I'm new to the skid steer world and hoping I'm not going to regret this purchase. Thanks!
