Alex DT 175 1974 Posted July 26, 2014 Share Posted July 26, 2014 Hey So I took the carb apart, replaced the O ring, the needle valve set and the gasket. I cleaned it up well with carburetor cleaner. Put it back together and now my bike start with choke and one kick. The thing is that the RPMs are really high and if I try to push the choke back in, the rpms get out of control. This doesn't make sense to me since I thought that when you pull the choke out is when you engage it and a richer mixture of gas goes in. For a moment I thought the accelerator cable was caught on something or too tight to I loosened it, but nothing. I tried playing with the air intake and the idle but no luck . And I followed the direction on the manual for one turn on the air intake Any ideas of what it could be? Link to comment Share on other sites More sharing options...

nayruf Posted July 26, 2014 Share Posted July 26, 2014 Hi Yeh, start a workshop thread, when you say the revs are high, if by mistake you have put the throttle slide in back to front the bike will rev really high as the slide will be held open, there is a little steel dowel pin in the inside wall of the carburettor body that locates the slide also you can see on the slide there is a little sloped portion that the idle screw pushes on, noting either of these will ensure that the slide is fitted correctly, I have fitted the slide wrong a few times, Link to comment Share on other sites More sharing options...
dt502001 Posted July 26, 2014 Share Posted July 26, 2014 Yep you got the slide in backwards. cut out part at the bottom goes air box side Link to comment Share on other sites More sharing options...
Alex DT 175 1974 Posted July 26, 2014 Author Share Posted July 26, 2014 I was looking at that for a good amount of time actually before I put it together. I will have to open it and see again Is there a reference photo anywhere? Sorry for posting on the wrong place Link to comment Share on other sites More sharing options...
Moderator Cynic Posted July 26, 2014 Moderator Share Posted July 26, 2014 It has a guide slot in the slide. That runs on the opposite side to the idle speed adjuster. That pushes on an angled part of the slide. Very easy to do. Link to comment Share on other sites More sharing options...
funkydruid Posted October 20, 2014 Share Posted October 20, 2014 Hi guys, new here. I have a '92 DT175 and I'm trying to tak the Carburetor off the bike. However I can't seem to detach the autolube hose, i don't want to force it in case I break something. Does it just slide off? or do i need to do something 'special'? I have a copy of the service and repair manual, but it's the photocopy one that's floating around and so the images are crap and therefore doesn't really answer my question. Any advice would be well received. Regards. Link to comment Share on other sites More sharing options...
Moderator Airhead Posted October 20, 2014 Moderator Share Posted October 20, 2014 I find it best to warm the tube at the spigot briefly with a hot air gun or a hair dryer briefly, It'll come off easily then. Dont go mad with the heat...petrol remember Link to comment Share on other sites More sharing options...
