Like Paul I tend to add Tetra Boost to the fuel. Haven't tried it on the Rosengart yet but with our Mini 30 (the standard 998 cc engine but with a Stage one kit fitted) even after having stood for nearly 12 month she started immediately. Furthermore I prefer to buy 98 octane when available bit with Tetra Boost 95 octane works okay as well. In the pas I have encountered starting problems with my TVR 2500 Vixen (TR 6 150 BHP spec engine on two SU's) when that on head stood for a prolonged period.
