[QUOTE="Normski, post: 94803, member: 3106"] It may be as Greg says, heat from the head transferring into the carb body and vaporising the fuel. Tickling would put a fresh lot of cool petrol in to counteract this. That would explain the contradiction of flooding helping a hot engine to start. Triumph specified a thicker o ring than the Amal one for the carb to manifold fitting which along with some stepped studs and rubber bits meant that there was [U]no[/U] metal to metal contact between manifold and carb. Even after a good thrashing you could feel the heat difference either side of this with the carb being cool - set up like this there was never the fear that a quick stop would lead to starting troubles. On my Egli I've monoblocs with 1/4" Tufnol spacers but there is still some slight metal to metal contact through the mounting studs, it's on the job list to insulate those too. As an aside I've never had carb icing with a Brit bike but it has plagued some oriental ones. [/QUOTE]
