It’s been raining for a while. Add together 18 hours of daylight every day and constant watering and the lawns are a rabbit buffet that will never run out. I need more rabbits.
Today wasn’t too bad so I wheeled out the lawnmower. A petrol one, Briggs and Stratton engine for those who care. It had been playing up lately so I bought a carburettor fixing kit and sorted it out. It cost less than £3.
I’ve fixed car carburettors before (back when they existed), both fixed jet (Cortina, often) and variable jet (Mini). The primitive lawnmower one was easy. It really is very primitive indeed.
It ran perfectly… for about 15 minutes. Then it died.
Took out the spark plug – covered in soot. Okay, fuel mix is too rich, how do I adjust it? Answer – I can’t. This little carb has no adjustments. Cleaned and regapped the plug and it fires up, then stops. Brrm-brrm-nah.
Well, buying a completely new carburettor will only cost £20. I could give up and do that. I could, but it would be an admission of failure. This primitive little engine really doesn’t have that much to it.
So off I went to YouTube for some help. It’s full of videos about the exact same problem, it seems to be common. The one tip I found that nobody else mentioned is that the gasket can creep back between the two fixing screws at the back of the fuel tank. A score line in the tank there will help it grip. Also, fit the O-ring and plastic retainer to the carburettor, not the air intake manifold. Nobody else mentioned that one.
Tomorrow I dismantle the mower again. I will try not to give in and just buy a carburettor but it’s a race against time here. The grass is fast reaching the point where it wipes your arse as you cross the lawn and I really need to mow the drive. It’s starting to look like something David Attenborough would drive along.
So this thing has had a carb overhaul, a new air filter and spark plug, a new paint job (courtesy of Son who rescued it from its final rusting place in the shed) and it worked well for a while. Now it has decided to be a difficult git.
I think the grass has bribed it.
