NonMember Posted April 9, 2019 Report Share Posted April 9, 2019 I think you're missing a spacer. The fast idle lever should not hit the manifold! Link to comment Share on other sites More sharing options...

Your right had a walk back in the garage tidying some spanners away and saw the thick spacer gasket on the bulkhead doh! all fastened up and not hitting the manifold. Cant see the wood for the trees sometimes lol. Link to comment Share on other sites More sharing options...
PeteH Posted April 10, 2019 Report Share Posted April 10, 2019 Hi On some vehicles that "spacer" is is of a non heat conducting material too. There was an issue in the 60`s, when mini`s first came out and guys swapped carbs; in the "hope" of "Go Faster". The spacer aided keeping the carb; cooler and fuel evaporation to a minimum. Leaving the heat shield off was another "mistake" often made too. A lot of "hot start" issues could be traced to that. Pete Link to comment Share on other sites More sharing options...
Pete Lewis Posted April 10, 2019 Report Share Posted April 10, 2019 my SU manual seems to say the heat/spacer is Phenolic a type of synthetic polymer Pete Link to comment Share on other sites More sharing options...
PeteH Posted April 10, 2019 Report Share Posted April 10, 2019 HI Would seem to support my feeling then, The "Mini Maniacs" back then would leave it out to give greater clearance, with the Carb(s) being close to the bulkhead it was sometimes a issue getting the shiny Intake "trumpets" to clear!. (Filter? what Filter?) What did not happen with many was they forgot that "breathing" was not just down to a "Bigger" Throat. But needed gas flowing and other changes to achieve any decent power increases. So often they where just wasting fuel and making life harder!. One guy sheared off the bottom of the SU carb, when the Head mount brace gave way. He was lucky not to finish up as a ball of fire, because the SU pump just kept on pushing petrol out!, even as the engine was stopping. Link to comment Share on other sites More sharing options...
