End of Week 13. Late again, this time because I've been unwell.
No oil and coolant usage as I've come to expect.
The biggest change this time around was fitting the newly rebuilt carburettor. Initially this was a little frustrating as the float behaved as though it was stuck, initially solved by swapping out the new float for the original. However, a drive the following day resulted in several failures to proceed with the same sticking float symptoms. A simple matter of pulling over, letting the excess fuel drain out of its own accord, restarting the car and driving for as long as it would before the needle stuck again. Tedious, but not particularly dangerous since I was so close to home when it happened on slow roads. Fortunately, because it was a friend that had rebuilt the carburettor, it meant we could have a chat about the potential issue and both agreed that while nothing looked amiss it did sound like a sticking float or float needle, so he popped some new ones in the post for me and once they arrived, I could remove the carburettor yet again to have a look.
Initially, nothing appeared amiss at all with the float he'd installed, nor the seat. Everything was still spotless and free moving. It wasn't until I got the replacement needles - fluted type, rather than triangular type - that it became apparent that the needle he'd used for the rebuild was ever so slightly off centre. Honestly, on its own you couldn't really tell, it was only when compared to another needle and in photographs that you could make out the slight deformity. I took three photographs with the needle resting on each side of the triangular body to show how minor a flaw this was.
With the replacement float needle and seat fitted, I also refitted the new float and checked the various measurements before reinstalling on the car.
The result was 10 minutes of happy idling followed by a day of trouble-free errand running. A frustrating problem initially but one that was thankfully easily resolved, it appears. With the new carburettor fitted I can get the car to idle at about 800rpm, the book suggests 750rpm. If I drop the idle below 800rpm, the engine cuts out so the next suspect item is the distributor which discussion has led to the theory that the advance springs may be weak. Fact is, the car is happy enough at 800rpm idle so, for now, I'm happy to leave it alone.
Next on my list is the front wheel bearing, a replacement kit - 2 bearings and an oil seal is required - is £15-20 delivered per side and the workshop manual makes it look like a fairly straightforward job. I have a couple of complete spare front hubs in my stash and I'll strip one of these to get an idea of how difficult the job might be before digging into the car, at least that way I'll have some idea of how likely it is I'll end up immobilising the car.
Since servicing the suspension the car rides much nicer on broken road surfaces and is considerably less bouncy, so I'm glad we did that too. Fuel economy is I suspect improved, but the figures likely won't show this because of the float needle issue, so I'll have to drive and fuel up a few more times before that becomes apparent. Certainly the car accelerates much more smoothly now and slightly more rapidly, which is welcome.
