0007 Posted April 23, 2013 Report Share Posted April 23, 2013 You don't need a carb you either need a needle and seat or a float Cheaper than a carb Quote Link to comment Share on other sites More sharing options...
overdale Posted April 23, 2013 Report Share Posted April 23, 2013 Steady on Bruce, 0007 is correct, do the floats float, as I have heard of one or both being punctured. Regarding the needle/seat, with the float bowl off, attach a bit of tube to the fuel inlet, blow gently into it then lightly raise and lower the float, when up some slight back pressure, when down none. Is there a fibre washer between the valve seat and the body? New bikes always come with nicks cut out of the two plastic overflow pipes which run downwards from the float bowl bottom and right hand side of the carb. If they are not nicked, if the carb overflows, you can get a syphon going. Quote Link to comment Share on other sites More sharing options...
bruces670 Posted April 23, 2013 Author Report Share Posted April 23, 2013 I've put the floats in a bowl of water and they seem fine,I will do the pipe trick and try that,it seemed to be worse this time when I put it back together,which needle and seat are you referring to? The float needle seat is in a recess and I can't see how it would be replaced? Quote Link to comment Share on other sites More sharing options...
0007 Posted April 23, 2013 Report Share Posted April 23, 2013 I suggest you order a new needle and seat When you have it in your hand it will become clear to you how it is replaced Also you may want to have a professional look at your carb anyway, maybe it would be best if a trials dealer were to install this and set the float height, I would assume at this point it has been messed with more than once and Needs attention Quote Link to comment Share on other sites More sharing options...

bruces670 Posted April 24, 2013 Author Report Share Posted April 24, 2013 Does anyone also with an evo know which pipes should have a slit in them? And whereabouts? Thanks Quote Link to comment Share on other sites More sharing options...
billyt Posted April 25, 2013 Report Share Posted April 25, 2013 (edited) Is it your emulsion tube?, bunch of tiny holes in it and a hood on top where it's exposed in the Venturi If so it goes in from the top and the main jet screws into it holding it in place Two two stroke carb does not have an emulsion tube. Emulsion tubes are for four strokes. Edited June 1, 2013 by billyt Quote Link to comment Share on other sites More sharing options...

bruces670 Posted April 30, 2013 Author Report Share Posted April 30, 2013 Altered the float height a little and it hasn't done it again yet but need a longer play on it to be sure,it was doing it when the motor wasn't running that's the bit I couldn't understand.
