So I just bought a 03 1300 bought it from a older man that bought it new and has had it every since last week until I got it. Say for 7 years. So when I got started drained all the fuel out went thru the hole carb multiple times all fuel lines clear new petcock and plugs as well. Now it will sit there and idle all day long can rev it and everything but as soon as you put it in gear and take off it’ll bog itself down and cut off. Will fire right back up and idle just fine then do the same thing every time. Anyone have any recommendations on what could be the next step or something someone else has come across?
