Update

I have been doing quite a a lot recently although I haven't really kept up with these blog posts or even photos. I soldered the fuel tank. I might still line the tank with something like Por 15 or similar to prevent it from rusting and helping to fix the leak. I've also done a lot of cleaning of various parts. Yesterday I took the valves out and cleaned and lapped them. Next up is to tune the valve clearances. Both of the valves have too small clearances which I should be able to fix by just carefully sanding a little of the shims with fine sand paper.
