2000 Vino Wont Run

[snoworshine]

Hey everyone I am new to owning a Vino. I was given a 2000 vino with 400 miles on it. It is basically brand new except for not running since early of 2002. I got the vino fired up with a huge cloud of white/blue smoke. I switched the fuel out for new fresh fuel. The problem is its not getting enough fuel to run any extended period of time. I think the old fuel gummed up somehere along the line. Anyone have any ideas as to where the fuel could have gelled up? My first guess would be to take what looks to be the fuel pump off and try to clean it. Any suggestions?

I'm afraid you're in for a thorough carb cleaning.

[snoworshine]

any helpful steps on the process?

carbs are easy to clean...

Simply (never done on a vino) pull the panels to get to the carb...

once you have done that, unhook the throttle cables and the fuel line..

Unscrew from the intake manifold..

open carb up and clean everything with carb cleaner..

you might need to buy a "carb kit" from your yamaha dealer or an online source... basically new seals (rubber o rings) and float and such... many times the float will have developed a leak and cause fuel to enter it... causing it to flood the engine and making it blow clouds of smoke out...

I'd also change the spark plug...

What likely happened is that the float and needle is stuck.
You can likely carefully take it apart and not have to buy anything.

More than likely when you try to take your carb apart you are going to mess up the gaskets. I would bite the bullet and get a carb kit before you start that way you don't have to hassle with getting the kit after you have little bitty parts all over the kitchen table.

Does it start after it sits for a long while and then only run for a few seconds?

[snoworshine]

yes it will start first immediate kick if i let it sit for a while, it will idle for several minutes or if i rev the engine it will not be able to run that long as it seems it runs out of fuel. Still a decent amount of smoke any way that it is running. Do you think if i keep idling the bike it might 'loosen' up everything in the carb?

the carb has a rubber "o" ring as the bowl gasket
it will be fine on reinstallation just dont remove it from the hole its in.
then as said, remove the screw that holds in the float.
spray some carb cleaner in the holes let sit &/or soak
(don't soak the gasket)
then use some compressed air to spray out the passages
try not to change any settings if you do remove any screws
REMEMBER to screw in the mix & idle screws, count how many turns each take to bottom out (don't force) ,write it down.
then when your done cleaning put the screws back to the settings you wrote down.
you might also clean the air filter and replace the fuel filter
for good measure
good luck

Yes, that's what I'd try.
The float and float needle are stuck. It they are not too glued in place they might free up. Also, clean your spark plug. I'll bet it's really oily looking.

[snoworshine]

Sounds good, thanks for the advise. I will clean the carb. Can I spray carb cleaner in the carb when the engine is running, maybe get lucky and save me the steps of taking apart the carb? The spark plug is basically brand new. The bike only has 480 miles on it. Basically brand new.. nice free gift. All i had to do was to have locksmith make a key for it (20$) and get it registered.

[scootertrash]

You still need to clean the plug. It's going to be covered in oil.
I don't think spray carb cleaner will do any good at all.

[StepVino]

Agree. That's twice in arow! ;wink)

Snow, it's real easy to take the bowl off, just 4 screws. You'll need
the practice anyway. Chances are the carb is going to come off
many many times for rejetting, so might as well get familiar with it
now.

Spray carb cleaner won't really work if you spray it in while running. It won't get to all the passages and jets. You could add a SMALL amount to the fuel tank, but DO NOT over do it. Read the container and add an appropriate amout for a gallon and a half of fuel.

I'd remove the carb and take it apart and clean it though. Take some photos as you take it apart (digital camera) and make an "exploded view" as you take it apart. You shouldn't have any problem putting it back together.

[powerzombie]

Oh yeah, don't get carb cleaner in your eyes or on anything rubber in the carb, it will eat both.

[harry]

the brass oil valve can be stuck open on that carb also
that would/could be what caused the scooter to smoke like a sog
when you started it
get serious and take the carb out and clean everything with the carb cleaner that way you know that the carbs good to go, and any other troubles you can rule out the carb as a source.. the tank method is not the best way
just have a golf tee ready to pulg up the gas line

BTW do not stick anything in the brass oil valve
use lots 'o carb cleaner and air

[snoworshine]

ok so i pulled the carb, cleaned it. reinstalled. the scooter wont start now. i manually shot some fuel in the carb and it runs, but for some reason it wont pull fuel on its own. Anyone know the trick? thanks again.

[scootertrash]

Did you make sure the float and needle are moving freely?

[snoworshine]

no i didnt check that. how would i do that once the float cover is placed back on?

[StepVino]

It won't start right away till the bowl fills with fuel.
That should take 6 or 7 electric start attempts.
You can speed that up by putting some vacuum
on the fuel valve/pump.

You can also unscrew the bowl drain plug, and see if fuel
comes out.

I assume compression is good?

[scootertrash]

no i didnt check that. how would i do that once the float cover is placed back on?

That's what I was referring in posts #5 and 10.
It's the thing you check while you have it apart. It's is the valve that allows fuel to enter the carburetor.
If it's stuck = no fuel for you.
