Yes Paul at times it was up on some very steep angles,probably 45 degrees I was trying to keep the carby on the lower side but could not use it that way all the time.
MF, this motor has done a lot of work so this might have been the last hurrah for the poor thing, I don't think the fact it is a PT that is the issue. I got it cheap because the motor had a strange noise when I tested it.Then I gave it a big kicking by tearing into that massive pile of kikuyu that was also full of rubbish you couldn't see till it came flying out the side.
