Tank fitted and heart pounding I added some petrol. The left side NOS tap was weeping all night so I had to drain the tank and re-cork the tap this morning. With that done there are no apparent fuel or oil leaks now.
The exhaust system is next on the agenda , But I decided to kick the engine over anyway. It fired on the first prod and then died immediately. This continued for a dozen kicks or so, until I gave it some choke, and it then fired up and continued running on a fast choked tick over until I pulled off the choke and it then ran quite smoothly, all be it noisily
However I'd momentarily forgotten that these are slack wire advance so I'd started and ran it on full retard.
I'll attend to the exhaust before a re-start. Ron
