Hi Grumpy, thanks for that explination, can now fully understand what was happening and why it continued to happen. You wont believe it but went to run the chainsaw today, 5 pulls and it wouldnt start, well what now. Had a look, stupid me forgot to turn kill switch to on, can you believe it. Anyways ran the chainsaw a couple of times today, started, idled and reved all without fail. Thanks heaps for your help Grumpy, its much appriciated.
