Not Rover specific, but relevant to any fault finding in general.
I have not been posting on here much recently, as I have been too busy doing an engine rebuild on my partners 1936 Morris Eight Tourer.
How she looked before...
It belonged to her late father, so no pressure to get it right :shock:
She had new big ends, new mains, relined and re-bored to standard size, new pistons and rings, new timing chain etc...
Finally the engine was back in, and I went for that first nerve racking start-up..... Eventually she fired up, but was running extremely roughly so I tried adjusting the mixture, slow running etc... in a bid to smooth out the problem, but to no avail
On top of that, when you switched off, and then tried to restart, she was having none of it :cry:
Since these are fairly basic engines, there isn't really a great deal to go wrong. I re-checked the valve clearances which were fine, the timing which was where it should be, I had fitted an electronic ignition before the rebuild so no points to check, and a new coil was also installed before the rebuild. I definitely had HT, as it gave me a belt when I was trying to check it by holding the coil lead near to the engine whilst cranking, but did show me a spark as well.
When I checked the plugs they were completely sooted up, which seemed to imply very rich mixture, but cleaning and re-fitting them had no real effect, and the only way the car would even start in the first place was if I had the mixture very rich
I decided I would reset the mixture to where it should be, clean the plugs again, and use my colourtune to see what was going on in there, but when I turned her over I got nothing, no sign of even a spark down the colourtune tube :shock:
I decided to change the new coil I had installed for the old one I had removed, and see if it made any difference.
Wow. What a difference. She started without hesitation, and purred like a kitten:- RESULT A little tweak of the mixture and slow running and she was perfect.
The moral of the story:- "Just because it's new, doesn't mean it's any good" :x
And how she looks now (with the old coil in place)
New coil in the bin, and another on order from a different supplier
