But no. The mower is having none of it. Starts fine, runs, revs up as it should, runs for fifteen seconds then dies back to barely a tickover. After a few seconds it revs up again and so the cycle goes on with the occasional stall.
It's had ethanol carp in all winter so obviously a blocked carb - presumably fuel flow restricted given the symptoms.
So, I dismantle the carb numerous times, remove fuel filter, substitute proper petrol pipe for the soft rubbish that I spot can stick to itself slowing fuel delivery. All jets out, all passageways cleaned and blasted with the compressor. A whole morning of frustration as the symptoms alter slightly but never go away.
So, as it's so obviously a fuel problem I take the plug out again and rather than just clean it as I have already done I close the gap a bit. Problem solved.
Torch spark plugs. I guess they must be one step up from a Bic lighter that has no fuel. NGK on the way. Obviously when it arrives I shall discover that the problem is the magneto/governor or whatever lives in the depths of the engine but a proper plug is a start
This last week I have felt victimised by the things in the garage. I won in the end but I'm not sure they aren't plotting out there each night whilst I'm innocently sleeping.
