Hey I'm new here and struggling to find online help for a dune/type off road buggy.....it has been running fine up until my son pulled a jump in it almost immediately after it landed it sort of sounded like it was running out of petrol but this was not the case. It will tick over and idle fine as normal and rev as not but as soon as you put it into gear it barely moves and feels like it starves of air or fuel. Cleaned airfilter and it doesn't have a fuel filter...I'm a little puzzled? It has a 125cc engine in it with only forward and reverse gears no foot clutch just gear rev go? I think it might be a lawn flight buggy?? Can anyone please help me thanks
