I had a similar set of symptoms with my 52 when I finally got it
together and running. Was nice and smooth in the garage. Couldn't handle
running after it warmed up. Naturally, I had the SU's rebuilt. Sent them
to Jim Taylor, in Arkansas. He did a fantastic job on the rebuild. I had
described my symptoms to him. He told me to put the carbs on without
tweaking them and --- if the problem wasn't cured, I should look at the
ignition system, especially the condensor.
To shorten the story, it was the condensor. It had a terrible
temperature coefficient that woul cause it to increase its capacity as
it warmed up from the engine heat permeating the distributor. BTW, I
kept it just in case I run into somebody who seems to know too much.
