Sunbeam s8 motorcycle, Black

1951 Sunbeam s8, owned by me for the last 9 years. Was restored some time ago but paint still very good, all original metalwork apart from carb and filter. Not been used for 4 years due to health issues but ran well and was in regular use prior to this. Now accepted i wont be riding anymore so I have tried to start but no luck, I think the carb probably needs stripping and cleaning also the fuel taps need new corks as are leaking. It will fire up if I squirt some fuel directly through the carb so can't be too much wrong but I don't have time to go any further.
