I am another bloke who looks at old posts. Now it has come to pass that today I found out with a VC Sports, what Jo & vccomm meant about this model needing the correct air intake. Upon refurbishing the VC it played up like Tiger's symptoms UNTIL I refitted the snorkel AND air filter (air filter was in pretty ugly condition) and then it went like a train, like I had hoped it would. Anyone know where I can get an air filter for the light green air filter box? regards all. [Linked Image]
