One advantage, perhaps the only advantage of lockdown is that we are forced to stay at home and not go ‘gadding about’ as we are normally inclined to do. So it was that after a most pleasant stoll in nearby Cirencester Park, Gloucestershire, as part of our permitted exercise, I found myself with a sunny late autumn afternoon to dedicate to the MG.
I decided to sort out the choke spindle on the carburetters (carbs for short) which I had managed to fit the wrong way around. What I haven’t recorded here is that I had previously corrected the throttle spindle which I had also fitted the wrong way around. Such is the lot of first time amateur car restorers such as myself, progress is riddled with little mistakes, however, with each mistake, I try to learn something. So to the choke spindle, which is an assembly comprising a spindle which sits within a cup on each carb (the MG has two). The choke mechanism operates when the choke handle is pulled on the dash. This causes the cable to tighten which, being attached to a lug on the spindle causes it to rotate. This rotation causes the choke mechanisms on both carbs to be operated because the ends of the spindles have lugs which fit onto the cams which themselves are on the end of the choke mechanism. The choke mechanism moves the needle inside each carb to richen the mixture, but also opens the throttle because the cams connect with a screw on the throttle spindle.
The fun begins when you realise that the spindles are not held in place in any way other than sitting in the cups on the carbs so when fitting the carbs you have to align the spindle ends (4 in total, 2 for the throttles, 2 for the chokes) with the cups, and have them aligned to the lugs (again 4 in total) while you are trying to to wriggle the carbs onto the mounting studs (4 in total). I make that around 12 points of contact which you are having to manage and it was certainly easier when I was able to phone a friend. To reverse the wrongly installed spindles, I loosened the carbs, but wanted to avoid taking them off as then you have to do the full accordian player impression as the two carbs writhe in your hands. The carb mounting studs are worth a mention, being located cruelly in the most awkward position and in perilous proximity to the razor sharp edges of the heat shield. It would be good to have three elbows on your arm at this point rather than the inadequate one we have to deal with. I won’t bore you with a blow by blow account, but suffice to say I got it all done in two attempts and only one skinned knuckle. I then fitted the air filters and went for a start up.
I connected the battery (ignition switch solution still pending), heard the familiar ticking of the fuel pump and turned the key. One click and then nothing. Mmm. I tried my spare battery, and it cranked over willingly but wouldn’t fire. Then I remembered to reconnect the coil wire I had disconnected. This time the engine started straight away, with full choke of course, and settled at a fast idle. After it had run for a minute or two I pushed the choke in and tweaked the idle speed to get it to idle correctly. I recorded the sound of the engine in the YouTube clip below. To get the authentic bass – use headphones. For an MGB is does sound rather tasty. Its obviously not set up right just yet, but it’ll do for the moment.
So that was a reasonable afternoon’s accomplishment. Today (Sunday) was a more gloomy day both weather and progress wise. A dull autumn day dawned and after finishing off the chores and watching Church online (another COVID consequence) I pushed the MG onto the drive intending to fit the engine fan I had bought recently. To get access to the pulley I determined it would be neccesssary to loosen the radiator and pull it away from the area. This is relatively simple on the MGB, being six 0.5″ bolts (what else) to remove. Having pulled the radiator back I realised that the fan I had bought was the wrong one – annoying as I thought I had searched it correctly. More catalogue searching required and another item for my MGB parts shop which I will be opening at some stage to sell on all the surplus parts I have amassed over three years. So I had to pointlessly put the radiator back again. It was then I remember that fitting the radiator is more difficult than removing it. The radiator is mounted by the aforementioned six bolts to a steel shroud which is fixed with eight bolts to the inner wings. The challenge is to get this all to align. The shroud in my MGB, despite being resplendant in shiny black from the paint shop, is I believe a bit warped. The off side is particularly difficult and I had to loosen all the bolts on the radiator and shroud on that side to get each bolt to bite on its thread. Having had this difficulty before, I was up to the challenge this time, and a bit of thinking and remembering got the job done in the end. All helped along by my Radio 4 soundtrack in the background, latterly a re run of ‘Just a minute’ with the late Nicholas Parsons.
