Well I picked up an Amal 75-145 carburetor for the real C12, that is off a B23. It has the extended body to overcome the dynamo. The one thing is the body needs a blanking plug for the back end of the air screw. Anyone know if itcis just a plug or shapedto fit the needle?

although the shaft is an odd shape the best way to "run in" the pump is to grip the shaft in you cordless drill and hold the pump firmly in you hand - works well and then strip it down again and wash it out thoroughly

Your in luck I have pulled one out of my old C11 engine that is part of a project I will be rebuilding in the next couple of years. It's in good condition and will get you going. PM me your address.

I have removed your phone No.  For safety as anyone can see it.  Best if they pm you.

Thank you for such a detailed response and for being willing to share your expertise. I will try it - I haven't had paraffin for a while - always liked the smell of the old heaters..

The problem is the Mazak monkey-metal body of the pump swelling from the impurities (acids, I presume) in the old oil that's left in it when laying up for a lengthy time, Steve. There are many previous discussions on here if you use the search thingy. The pumps wouldn't be a problem if owners changed the oil and fired the bike up and ran it for a couple of minutes before standing the thing up for the winter or longer.

The best way to clean it is to use a sharp, pointy tool, like one of those pick sets that you can buy cheaply from a tool stall on the market. The fungus stuff just needs picking and scraping out of all the corners and then the internal flat faces cleaning up on an old mirror with paraffin and wet-and-dry or valve grinding paste. It's best, obviously, to replace the internals back in the same position as they came out of.

I like to be able to turn the gears with my fingers when the pump is reassembled and, if it's a bit stiff, then spinning it in a bowl of paraffin with a cordless drill will usually fix it.
