Engines / Lister cem governor to fast at idle after rebuild
« on: November 15, 2020, 10:44:53 PM »
Hi, I’ve just rebuilt my 1939 Lister cem (the marine version of the ce) I’ll post a video documentary soon. Before rebuilt the idle was slow but irregular, and during rebuild I discovered that the springs on the governor weights were not there. (I had wondered what the clanking was at slow speed) on assembly I fitted the springs from a spare marine ce engine I have, and since then The governor does it’s job well, although the slowest rpm it will work to is 560rpm, which in my boat and prop is to fast. I’ve heard rumours that Lister recommend idle of simular engines at 450rpm. Really I’d like to achieve 250rpm which it runs happily at (but not governed) I’m thinking of adding weight to the governor weights, my idea is to build a test bench with the spare governor, Spin it to the current 560rpm make note of where it opens, then try and add weight until it opens more, then  setting the rpm on the test bench to the desired 250rpm, to the point that it will shut the fuel rack to run at the desired 250rpm. Does any have a view on this idea? It’s a big mission to get to the governor (remove flywheel etc) so I need to be confident it will work. Thanks guys
