: My Dad has a WD45 that we just can't get to perform, I know it should be able to do the things we ask of it but it just doesn't want to! When under load it sputters, backfires and it just dies. The carb is clean, needle is clear, points changed, timing changed, plugs, wires, cap, it is when it needs power and the gov should kick it up it just dies. Any suggestions for us rookie farmers! Thanks!
