Jobs you haven't done before, especially when the internet is full of forebodings of woe, seem a bit daunting. When it all goes well and may even appear to have been some use, I wonder what all the fuss was about.
Starting isn't one of Tortoise's BMC's fortes at the best of times. One thing I wanted to check was the glow plugs, so I hoiked them out one at a time and had a look. They all glow nicely when powered up (albeit taking a while to get to red hot), so there doesn't seem to be any rush to buy new ones quite yet.
Three out of four, though did seem to be pretty much bunged up with carbon - I cleaned out the holes with a 4mm, then 4.2mm drill bit, which seemed to do the trick. Tony Brooks et al suggest 11/64", approx 4.35mm, so I should be OK. I did worry about losing the drill bit inside the engine block, though.
Afterwards the engine started OK, but it often does, so at least I hadn't made it worse. The electrics leave something to be desired though - the voltage at the starter battery (itself an old domestic one of unknown history) when the glow plugs are running is less than 12v, and there's a 0.7v volt drop to the glow plugs. A new starter battery (anyone used a smaller 40Ah car battery as a starter - any reason why not?), and/or thicker wires for the glow plugs (or even better a local relay connected to the starter volts into the solenoid) would improve things no end.
No pictures, although I really should have taken some.
In other news, it's Towel Day on Wednesday, and just in case you were wondering, wikipedia have a lengthy article on the meaning of life, so we need wonder no more.
I'll have a wander around Rickmansworth festival on Saturday; it beats working.
Near disaster but all's well - You all remember our little Ronnie the Chorkie Grace's dog I suppose you would call him, but he's a family pet anyway and a regular boat crew member. Well ...
