Stasch Posted September 28, 2010 Share Posted September 28, 2010 I recently acquired a 74 DT175(A?). I have a Clymer Manual which is maddenly evasive in stating the proper float level height for this carb. The Float Level table in Clymer page 86 only shows info for these models: GT Series, YZ80a, DT100A, MX100A, AT1 series (and MX), AT2, AT3, AT2-MX, ATMX, DT125A, MX125A, YZ100C, YZ125A, CT1 series, CT2, CT3, DT125A, MX175A Is DT175A the correct designation for 1974 and could it be equivalent to AT2 or CT2 or CT3? Thanks! Link to comment Share on other sites More sharing options...
Moderator Cynic Posted September 29, 2010 Moderator Share Posted September 29, 2010 They all use a variation of the Mikuni VM24 carb, be it bigger or smaller, newer older and the float height is 21mm. Bit more info, DT175 A/B Mikuni VM24ss 160 main, 5G4 jet needle Clip 3rd groove from top Pilot air screw 1 3/4 turns out Float height 21mm +/- 1.0mm Idle speed 1300-1400rpm Link to comment Share on other sites More sharing options...

Richie_31 Posted September 3, 2011 Share Posted September 3, 2011 Hi Cynic! Thanks for this info. How about Mikuni Carb VM26SS and TM28-92 for DTs particularly on Pilot air screw turns. Is it the same as VM24SS? Thanks Link to comment Share on other sites More sharing options...
