Haven't got much done these last couple of weeks I'm afraid, but I've spent a few hours here and there sorting some of those annoying little jobs, but other stuff has kind of got in the way.
Things I have got done though, about a week ago I dismantled the steering column for a couple of reasons: firstly to move the wheel a couple of inches closer to the driver for a more comfortable drivingh position; and secondly so I could remove the indicator switch and clean up the contacts - the indicators were running at a frustratingly slow 55 flashes per minute, too slow for the mot, but wiping forty odd years of crud off the contacts has sorted that and they now run at 65 flashes per minute.
Next job last week was to adjust the mixture on the carbs as it'd been far too rich. For once the Haynes manual was actually pretty easy to follow and it only took ten minutes to get the mixture near enough for the time being. It now needs the choke to start from cold which it didn't before.
Last job, which I tackled today, was to try to establish why I was getting no heat from the heater. I had my suspicions that the water wasn't flowing through the system properly so I disconnected the heater hoses, put them in a bucket and ran the engine to see how much flow there was. Answer, none.
I decided to start removing the hoses around the system to see if there was an obvious blockage and quickly found the problem -
It turned out that the whole of the heater circuit was completely blocked with a solid sausage of rusty sludge. Using the special tool you can see poking out of the carb pre-heater tube (an old wire coathanger), a slim screwdriver and a garden hose jubilee clipped onto the hose connectors at various points, I eventually restored the flow through the heater pipes.
I've connected the ends to each other with a length of copper tube for the moment, I want to thoroughly flush the system with Radflush and refill it with fresh coolant before I reconnect the matrix. Hopefully I'll have a working heater tomorrow. Given the weather we're having at the moment I'm rather glad I decided to include that particular option.
An unforseen problem surfaced as I was packing up this afternoon though - the horn suddenly started sounding itself for no apparent reason. I whipped the horn push out, then took the steering wheel off but it kept going so I had to disconnect the battery.
After lots of head scratching and a bit of prodding with multimeter probes I think I've found the problem - when I put the steering column back together it looks like I've pinched the live feed to the horn push under the edge of the metal cable tidy that guides the wires coming from the steering column switches. I think it finally cut through the insulation and earthed the horn circuit while I was connecting up the heater motor switch nearby. Oh well, just another job to tackle tomorrow I suppose.
Aiming to spend most of tomorrow working on my car so here's hoping I can get a bit more done.
