I've only had my '55 A7SS about 6 weeks and because of a few starting issues, I decided to get myself a replacement parts kit for the monobloc carb. This has certainly helped and it now generally ticks over quite nicely...but having taken the bike on two runs since (only about 10 miles each), it will only run whilst the choke is partly on. This made me think the bike must be running lean, but when I removed the spark plugs, both are sooty black! So now I'm somewhat confused on which way to approach this and any advice would be gratefully received.
Another thing that I could do with some help with is the operation and use of the advance / retard lever. Having been predominantly a japanese bike rider for many years, I've never needed to worry about such things. When I bought this bike, the previous owner said he never bothered touching it, so up till now, I haven't either. However, if I had a better understanding of when and where I'd need to use it, I might wonder how I've managed to get through life without it!
Thanks,
Steve
