So now it's off, I've removed the two rubber seals and have immersed in some petrol - only the end bit, not the plug end - there's nothing that moves though as far as we can see - so do we just leave it soaking ?
Fill it up with wd40, petrol won't do a great deal, let the wd40 soak in and then empty it out and then clean out with the petrol, or carb/brake cleaner
