OK, thank you.I will have another look at the carbs. I used a carb refurb kit when I first got the bike (as it was non-running) from David Silver. I kept the needles, jets and screws the carbs came to me with, so I'll clean them and the carbs and try the old ones again. No idea whether they're original Keihin brass though. I suppose it's possible, but unlike,y after 47 years and 42,000 miles!....
Martin,You need to renew the needle jets as well, they are a press fit into the carb body under the emulsion tube you refer to.Just tap them out with a pin punch from the top.The needles will be worn as well, when compared to new ones you will see the lower part shiny where it enters the needle jet. Genuine Honda needle kit 16012 392 004I change mine at 12-15000 miles, by that time the consumption has gone up and it'll start almost without choke.Good luckSkoti
