Whatever one of those is

It would be a pretty old picture if it is

Only in sailor's bars at the weekends

Is it? I think you'll find it is the O ring that goes between the top and bottom halves of the head Richard

Ahem... Frogs up below ground, frogs down above ground Do they come with a box of air gun pellets?

Yes, we had that problem. For a while we got showers of shredded insulation as it tunnelled it's way around No idea what happened to it, it's desiccated body is probably still up there Richard

I'm hoping that the next time you are on the water, it won't be a Kelvin

Just in case, I've seen the Redshaw filter and it's a very nice piece of kit

I look at it this way. After the tank, you've got a current industry standard 296 (probably) filter. Followed by a Lister woven sock filter, state of the art for the 1940s. I don't see what it is that the Lister filter can be filtering if the CAV one is working. And if the CAV one doesn't work, there's a good chance the Lister one won't either as it doesn't filter so finely Richard

Then leave the socks out and use the external filter to do the filtering

With the sock taken out of the Lister housing Richard

It would largely depend on who decides to vote

New pump - no. Seal kit, not sure. We haven't tried to find one for a couple of years Richard

This is the important bit, just to amplify the point. If the spring is always in tension, there is always an opposing force on the governor and it will be following a linear change If the spring lets go, you get step changes from something to zero, then back to something again. Not helpful. You can get this with the internal spring on the more modern Listers The extra spring in the mechanism is even more likely to give weird results. Putting one spring opposing the other adds the rates together, increasing the force on the governor - not what you'd expect. And if either of those ever goes loose, things will be all over the shop. Thanks for this stuff, Geoff Richard
