Serendipity city, part 2: Toyota Corolla

Here I was, thinking serendipity simply meant “happy accident”. But as The Teknologist writes, there’s also the educated guess side of it. Serendipity was coined by Horace Walpole in 1754, based on inspiration from the Persian fairy tale “The Three Princes of Serendip”. The Princes make some very good guesses, in their travels. There’s also a story in there, about dividing up eggs with a Queen, that Benny Hill would have been proud of. Let’s just say testicles are mentioned.

I wrote previously about how repairs on my Subaru Vortex XT were helped by a serendipitous sunroof. Well, just a few weeks earlier, the legend of the three princes helped with a Toyota Corolla that was running rough.

The 1.6 litre engine (carburettor, no EFI) in the 1991 Seca seemed like it was missing, with fuel not being burnt in one cylinder. So I had my mechanic take a look at it. After inspecting the distributor, he figured it must be the leads or spark plugs playing up.

Cylinder-by-cylinder, he got me to start the car while its lead was disconnected. The problem seemed to be pointing to (I think) cylinder 3. So, as a final test, he changed the plug and lead for that cylinder – and found that the problem remained.

Just as he was about to throw his hands up in the air and curse an automotive mystery, he was visited by a very old memory: that Toyotas from 30 years ago often had a diaphragm in the carburettor break, and this allowed fuel to get into an area where it shouldn’t be, causing what seems to be a misfire.

He said it was something he hadn’t through about in many years, as fuel injection is so common now. He dismantled the carburettor and sure enough, the diaphragm had just a tiny tear in it. It was barely visible, but enough to allow fuel through.

The solution was to order a carb kit for the Toyota from the auto store. He got on the phone and was told it would take a day or so to arrive. This prompted him to recall how, decades ago, auto stores would have carb kits sitting on the shelf because they were in demand. These days, not so much.

On arrival, it was but a small part of the carb kit that was needed. I’ve kept all the rest of the kit in the glovebox, for future use if required. Unlike the Princes of Serendip, I can keep those eggs in the one basket.
