Lambretta J50 Deluxe fuel flow problem fixes.
_Fuel
level Shown
In Red.
_I
started having problems with the Lambretta J50 motor cutting
out, about 10 miles from home. This would
_happen
every time. I started checking the fuel level and carburetor
before my scooter rides. The fuel level
_look
like Drawing 1
below. About 10 miles out, the motor started to cut out. I checked
the motor
_and
fuel line. It look like Drawing
2 below. (no fuel in the line) I took the
fuel line off to see if it
_was
blocked. The fuel flowed out with no problems???
_For
the most part. I think it’s a vacuum problem cause by the
fuel tap and carburetor.
_I've
seen this, same type of problem happen on the LD's.
_On
Drawing 3 below
I made a extra vent line that runs to the top of the fuel cap.
_This
fixed the motor cutting out problem. I now ride the Lambretta
J50 Deluxe on long-distances rides,
_all
the time with know problems.
_The
air vent line needs to be above the fuel tank. I tied my vent
line to the gas cap and
_put
little tubes in the tip of the line to keep dirt out.
