May 22, 201016 yr Hi, My Sherpa is fitted with a 27mm Amal Mk2 carb (spanish), Im new to Bultacos and the bloke I got the bike off told me it was not the original carb. Is this correct? Is 27mm the right size and if so what jetting would be standard. Ive got loads of Amal bits and pieces so I can play about to get it right, but a starting point would be good. many thanks Stu
May 22, 201016 yr 190 is a 250cc model and would have had a 27mm MK2 Amal as standard. Main jet probably 150, pilot 20 or 25, slide probably no. 3. This is from poor memory, Bultaco UK can advise on jet sizes and supply if necessary.
May 23, 201016 yr Author So Im not a million miles off, many thanks Woody. Will give Bultaco UK a bell (just bought a conrod off him, excellent service).
