Good point i'll check its location on the original motor. I might be able to get hold of one but will be interesting to see the temps either way. I may have found atleast part of the problem, seems my cowling is missing the black shield above the muffler as seen on this mower. Also stumbled across a picture of another mower missing the shield and the cowling was badly melted.
