Completely agree with both of you, Mahesh and Jonners, just a clean and scrub up, I would get a full refurb kit from Burlen especially as you'll be using it every other day. It has taken me ages to get to the point where I'm at with mine and that includes getting Burlen to do the bushes, the beading process and the plating of all of the choke parts to restore them to original spec.
I may add that one of the benefits of glass beading the castings is that it closes the pores on the metal which makes them easier to keep clean, but I have an irrational hatred of polished dashpots.
If you can get some, CarPlan do some brake and clutch cleaner which is great, failing that Jizer is really good. I wouldn't put the castings/bodies in the dishwasher though, they will oxidize! Just use some good degreaser and a toothbrush. Rinse everything in really hot water, it evaporates fast so you dont have to use an air line to dry parts and lay everything out on a table on clean kitchen towel.
One important thing to remember is not to mix up the dashpots and pistons as they are matched to each other. If you want to do a drop test use some foam ear plugs to block off the holes and hold the dashpot upside down on a tissue, you'll probably be fine though.
Can you do me a favour, can you take a photo of the inner choke linkages with the springs before you take them apart, I can't find my reference photos.
Actually when are you looking to do them? You're in London, I'm in Fleet, if you clean up the bodies I'll give them a bead blast in the cabinet for you.
