Yamaha Aerox 50 LC 2013
A neighbour got this for his son as runabout
I sorted a brake problem on it a while back and it went through the MOT OK.
But
Its not running right he says.
Smokey, black sooty plug, air filter wet with fuel
and just dropped of the carb for me to look at
It's a Minarelli Gurtner PY carb
Heres the overview pic with the main jet and main nozzle removed and lined up

Here's the nozzle dropped in with the carb held upside down
and the nozzle protruding a bit which looks pretty normal to me.

Now heres the bit puzzling me.
With the main jet fitted and the carb held upright
the nozzle drops down into the body !!
( yeah I see the tick over screw is rammed home, will back it off later)

I measured it all up and there's about a 3mm gap between the inner main jet and nozzle
All the fiches I've looked at showed no other parts in there so nothing appears to be missing
Surely that nozzle isn't supposed float about?
I would expect it to be a press or interference fit
or at least have an O ring or summat but an O ring might
drop the nozzle lower and interfere with the mixture
I'm tempted to mix up a wee drop of petrol proof epoxy and
carefully glue the fecker in but in case I've missed something
Opinions? ____________________ bikers smell of wee |

The tube definitely shouldn't rattle about like that. Looking at some parts diagrams (and loads of people make knock-offs of this carb) it's not showing any O-ring
Maybe get a new carb, as they're so cheap. ____________________ Husqvarna Vitpilen 401, Yamaha XSR700, Honda Rebel, Yamaha DT175, Suzuki SV650 (loan) Fazer 600, Keeway Superlight 125, 50cc turd scooter |
