I have been working on this scooter that has been sitting for a couple of years.  Pulled the carburetor and cleaned it, thoroughly.  Idle jet was a little clogged, but all else seemed good.  Float needle valve moved freely.  I tried to start it for the first time, today, and fuel was leaking from the carburetor drain hose.  This hose was cut off when I bought the scooter, so I just replaced it with a length of fuel hose.  There is no screw to open or close the drain, as far as I could see.  I've read that some of these carburetor drain hoses actually hook up to some sort of port.  Mine is just hanging freely.  I realize that the valve may not be seating completely, but all seemed good when I cleaned it.  Any thoughts?  Thanks, in advance!

Please forgive my ignorance!  I'm working on a JCL MP-150A that has been sitting for years.  Both left and right master cylinders are shot.  I've purchased the right (front) master cylinder, but the company didn't have the left (rear) one.  I am having the hardest time finding the rear master cylinder!  Mine have the banjo bolt coming out of the bottom of the brake fluid box.  Several of the ones that I see for sale have the banjo bolt coming out of the back of the box.  If the measurements are the same (especially the handle bar measurement and banjo bolt thread measurement), will I be able to use this in place of my frozen original master cylinder, even though the banjo bolt is in a different location?  Is it better for me to simply look for a rebuild kit?  Thanks!

Thanks!

You have been a tremendous help! Just one more question...on picture #2, next to the drain hose, is that a port for another hose, possibly to go to the smaller port on the bottom of that canister? The guy that I bought if from told me that it wouldn't idle well (it was surging...it would idle, then speed up, then idle, then speed up) and had a vacuum leak (bad line, according to him), so he started unhooking a couple of hoses, and eventually just stopped fooling with it. It has been sitting for a couple of years. Thanks, again, for your help and patience!

Thanks for the quick response!  I've tried to attached 3 pictures.  I don't know if they will show up, or not.  Anyway, in the image of the canister, there is a large nipple and small nipple on the bottom side.  The large nipple can be seen in the picture.  The small one is hidden.  there are 2 hoses connected to the top of the canister, so I'm assuming they're ok.

In the picture of the bottom of the carburetor, the hose that is shown isn't connected to anything.  This may be a drain hose.  The other port has no hose connected.  I don't know what that hose would connect to.

The third picture shows a hose coming from what I think is the valve cover.  It isn't connected to anything on the other end.

Well...it showed that my pictures were downloaded, but they're not showing up.  I'll keep trying!
