After my little rant about these Hondas, I put one of them up on the bench to see if I could see what was going on with them as I had already fitted a new carby to this one a few months ago. I had just pushed them aside for years but thought a new carb might help. Anyway on close inspection I was able to see that the choke was only closing about half way, so with a bit of bending and pushing on the choke arm and bending another part of the throttle control out of the way the choke now fully closes and it started without aerostart. I will see if it will now start from cold in a couple of days. Fingers crossed
