    I have a Lister D which normally runs at 700rpm but at the end of last year I had a problem with a split in the cooling tank. I dropped the speed to 600 rpm, there was less vibration and the leak was less. I have fixed the tank over winter and I'm thinking of carrying on at 600rpm. Any thoughts please. Is the plug likely to soot up more etc.

    You could but as the engine uses splash lubrication you would reduce the lubrication of the engine and cause possible damage.

    It will probably be fine at low load. Lister sold a 1hp at 500rpm D type. Just make sure the oil is kept topped up.

    I never thought about the lubrication, that is a very good point. I fibreglassed right round the inside of the tank which has cured (hopefully) the leak. I also stiffened up the trolley which should reduce vibration. I think I will go back to plan A and run it at 700. Thanks for your help

    when the engine is working it needs speed to help the lubrication as dan said, on no load it needs very little, so slow should be ok. it will also reduce your fuel bill!
