So today, thought it deserves a treat, cleaned front seats with Lidl W5 Cleaning Foam, they came up quite nice, drying off now.

Took distributor cap off, no trace of condensation there, slight staining of inside of cap, so wiped it out, sprayed with WD40 and wiped out again.

I did notice that the carbon brush was fairly worn, but OK, I compared it with the brush in a new cap.

Started the engine, to my surprise, the tickover was smoother. I don't notice any difference in the rev counter.

Bonus, that slight bearing rattle that many 340's give at tickover, has reduced to almost non existent. I've never taken engine/ transmission apart on a 340, so not familiar with this bearing. Can someone explain about this bearing please?

I'm pretty good on mechanics, in fact I used to work for Janspeed in the early 70's. Rebuilt many engines / gearboxes, mainly BMC A series Mini, including the BMC Mini auto box.

340's don't have any bearing rattles they have hardened crankshafts. You might find the valve clearances need adjustment :-)
wow the mighty Janspeed , did you make the manifolds ?
