Early DCOE's with brass shafts - so problems ahead!! Seized cover screws have to be milled out before......
.....we can start dismantling the internals.
CO&PR involves full overhaul, full ultrasonic cleaning, re-engineering visible external surfaces and linishing, polishing and replating all external steelwork. Then a very careful rebuild before testing.
Hopeless? I do not think so.
What a mess!! However technically, the only problem is leaking choke circuits and arrangements were put in hand to effect a permanent cure. This is a common problem on higher mileage Webers ( the cold start arrangement on Dellorto DHLA's is far more reliable).
Same carburettors, after CC and PR.
So here is the results of a lot of work. No acids or aggresive chemicals used, just time, ultrasonics and sound engineering practices.
No point in wasting my time and my customer's money restoring surfaces that will not be seen.
Cold start internals are all back in place, but the operation is being disabled: an alloy plate will be fitted and the cold start circuit plugged. No silicon squirted hither and thither - rather an engineering solution.
A visually pleasing, fully functional and tested set of early Weber 40 DCOE's ready to be refitted to theS3 Elan they came from. This set of illustrations may serve to show what is possible. Nothing left to chance - no aggressive chemicals or acids. New Weber overhaul kits fitted, key parts replaced and all accurately built and tested.
