Fuel Leak

Postby peteld » Thu May 09, 2019 11:21 am

Hi Guys

I took m minor out for a short little trip today, had the bonnet open and everything looked good.
when i came back, i noticed fuel leaking from the carburettor float lid (see picture). I took it off, and checked the float, pin and so in, everything is moving as is should, and generally in good shape...
after reinstallation, i turned the key to ignition, and the fuel pump ticked as it should, no leak.. took it for a short drive again, and when i came back, fuel was leaking again... any suggestions what to do?

That's where the float chamber over flow is positioned. It will either be a piece of debris stuck behind the seal of the float valve, a sticking or punctured float or possible a damage float valve seat.

What type of float is it, brass or plastic? It could be punctured and have fuel in it making it heavy. Give it a shake to see.
If it's brass it's an easy enough fix, put it in a bowl of water and look for air bubbles. To fix it, remove the fuel inside and solder the hole. If it's plastic then you will need a replacement float.
