My McCulloch FR44 Gas Trimmer suddenly lost spark.
Got the neighbors old MAC 2816 Trimmer which blew up from the wrong gas-oil mix for the ignition-flywheel pick-up but need the air gap adj for this. Part nunbers in the ign module are the same. Tried different gaps but still no spark. Starting to think that mabey right and left gaps are different?
Thanks in advance,
Phil
