smelling123 Posted April 13, 2014 Report Share Posted April 13, 2014 Bit wierd but my recently acquired 340 has a 36mm Bing ! I am assuming this has been fitted in error? I'd guess 36mm would be about right for an MX engine. I was pretty sure they came with 28mm??? Also, is the standard 199b (11t x 39t) gearing the same on a 198b or did the 250 have diffenent gearing? many thanks! Stu Quote Link to comment Share on other sites More sharing options...
pschrauber Posted April 13, 2014 Report Share Posted April 13, 2014 It should be a Bing model 84, with 28mm bore. main 125, idle 40, needle GG1, slide 0 Quote Link to comment Share on other sites More sharing options...
