mudyman Posted March 2, 2012 Report Share Posted March 2, 2012 Hi all other swm friends has anyone got details of which jets, slide, needle etc. should be in the carb of a 1984 Jumbo ? Thanks Ian Quote Link to comment Share on other sites More sharing options...
martinm Posted March 2, 2012 Report Share Posted March 2, 2012 (edited) Hi Ian That will depend on whether your motor has the reeds fitted or the blanking plate. The diagram below shows both jetting options. (Figures in brackets are if reeds are fitted.) Edited March 2, 2012 by MartinM Quote Link to comment Share on other sites More sharing options...
mudyman Posted March 4, 2012 Author Report Share Posted March 4, 2012 Hi Martin ! Thanks for the diagram. I just have a question about the things listed: Getto minimo = idle jet pillo conico = needle jet Valvola gas = is this the slide or main jet ? Polverizzatore = is this the atomizer ? Some of the things I could get translated but not all as my Italien is 0 Cheers Ian Quote Link to comment Share on other sites More sharing options...

geoff850 Posted December 10, 2019 Report Share Posted December 10, 2019 If my interpretation is right this looks like a pilot jet of 50 ( without reeds ) but what about the main jet? looks missing from this photo? or is this the atomiser? this is smaller than a 280 engine pilot '60or 65?

Main Jet = 100. Atomiser = emulsion tube = Needle Jet. AS 272 (no reeds) or AS 268 (with reeds). https://www.dellorto.co.uk/shop/dellorto-motorcycle-carburettors-parts/carburettor-parts/phbephb-parts/as-type-atomiser-phbh-phbe/ Needle is X2, SX 200 doesn't exist as far as I have found. Pilot = 50 (no reeds) or 60 (with reeds). Slide = 60 (no reeds) or 70 (with reeds). 1 Quote Link to comment Share on other sites More sharing options...
