    Yup, you are spot on I just adjusted the low speed and it's running fine again. The HT lead had come lose at the condenser, not all the way out, but enough maybe. Anyway, you lot are excellent, thanks for all the great help. I have a muffler with the baffles taken out to put on this saw.:D

    Walbro carb.
