240 1978 245L with B21A and SU HIF6 carburettor that has enormous gremlin
I have typed this all out several times but I get to the bottom of the post then everything collapses so I'm going to post it in several parts as comment or something.
I bought a 245L the other day from a friend who bought the car from the original owners at the end of last year. He warned me of an intermittent bog/miss that would happen occasionally but could not replicate it when he took me for a drive. When I picked it up the car idled perfectly for about 40 minutes and drove well for a short time before the problem first happened for me. I drove it about for about 100kms and the car behaved perfectly for most of the drive besides the occasion bog/miss that would make the car shunt briefly before coming good pretty quickly. I drove it again for about 45 minutes a couple days later and again it worked perfectly for most of the time besides a couple of misses but then the problem happened so bad the car coughed itself to death. it tried for a long time to get it started but it wouldn't start up again and had to be towed home. Since then it has started again and will occasionally idle well and other times will hardly run. Each time I have started it again after the time it had to be towed it will cough itself to death at some point.
I will post a bunch of photos and videos in a comment because I keep loosing everything I type when I do so
