British Bikes / problem with sunbeam s8
« on: May 09, 2007, 02:12:06 AM »
recently pulled my sunbeam s8 1954 from the back off the garage. drained the fuel and put fresh in. took a bit off time to get going running but got there. when you try to rev it, its a bit rough and black sutty smoke. checked a few things but no luck. anyone got any help and pointers how to solve.
