Nice on Arthur, the day I got mine back on the road, I went for short test ride up the hill (about 5 miles), but on the return, as all was well, decided to go right instead of left and did about a 30 mile blockie- no tools or anything, no probs. just couln't get the smile off my dial
Re the jet block, I figured the screw is just a locating pin rather than a locking pin ,'cos on mine it doesn't engage tightly with the block, just goes in the slot and the block is held in place by the jet holder ....?
Mind you, it is on the rich side, and I've played around with jetting and ended up with a .105 needle jet..
......but before this becomes a carby thread......didn't mean that though to be more than the first short comment...
