Thought I’d update this, as I’ve been doing more tinkering and experimenting. I’ve swapped the 20w50 in the dashpots for ATF. This has made a big difference, both to the ability to rev, and the ease of starting from stone cold. Previously the car would turn over several times before starting from cold, now it’s much quicker with only a little choke.
The manual suggests straight SAE20 oil, which in theory the 20w50 should be when it’s cold. I think ATF is 10w, so lighter than the recommendation. Whatever, this has made the engine feel much livelier. I’ve also bought a job lot of assorted distributor springs, so I’m going to attempt to restore the original factory advance curve, then see if I can develop things from there.
