jcsumm Posted May 14, 2010 Share Posted May 14, 2010 hello - i recently fired up my 1973 rd 250 and noticed gas leaking out of the bottom of the carburetor. upon closer inspection, there is a nipple located on the bottom front of the float chamber with no tube attached. i have searched and not been able to find any disconnected tubes. my question is: should there be a hose attached here and, if so, to where does it connect? thanks, jc Link to comment Share on other sites More sharing options...

It does'nt connect to anything, but it should have a length of tubing to direct the over-flowing fuel away from the motor. This usually exits behind the engine. Hope this is of some use Link to comment Share on other sites More sharing options...
Moderator mervin Posted May 14, 2010 Moderator Share Posted May 14, 2010 Ok the tube is not your gretest problem why is gas leaking out is your problem, well the float is set wrongly ir their is dirt in the float needle/seat area so the gas is still flowing when it should stop, are you familiar with carburettors, if not maybe get a manual and take em off and have a go at cleaning them yourself, oh and for all RD related stuff come and visit us on the aircoooledrdclub site Link to comment Share on other sites More sharing options...
