foxmoth Yes, you want the prop in the 2o'clock position rather than 12 or 4, both of which would be very awkward to swing. Prop can be bolted on in any of these positions
thanks, so was he verifying that the prop was correctly installed by moving it to its 2 o'clock position (for ease of propping) while listening for the impulse coupling click signifying that cylinder #1 was its firing position and feeling for the compression resistance. ( I assume the click only happens when cylinder 1 is at its firing stroke?
