Doug, thanks for confirming that my old cylindrical springs are not correct. I have fitted the 4 new barrels to the engine. My doubts were fired up by the 1930 EW Care and Maintenance booklet which appears to show cylindrical valve springs in the cutaway sketch on page 5. Regards, Ralph
'kev, thanks for the tip - I hadn't thought of the drill press. I use the bathroom scales on my 20T hydraulic press - that way I can tweak the spring length with accuracy. Cheers
