my dt50mx carbeter is poring out bensin from a hoal from the carberater

simon kronström /

I just changed the jet on the car an when i put it back togheter. so Did it start poring bensin from the middle hole in the carb.

does anyone know why it doing that. It dident do that before.

My moped starts but leaks bensin all over the steet from the hole. (edited)

Probably because the float is stuck open. (edited)

The float both closes and open as it shod do

Re: my dt50mx carbeter is poring out bensin from a hoal from the carberater

The float may be opening and closing as it should. But I'd bet that the float valve is not sealing completely. Does the leaking occur only when the bike is running? Or, if the bike is NOT running, with the petcock in the open or run position, does the carb also leak?

The carberater leaks only from the hole on the air intake. The carb leaks even if the moped is off

Yeah so the needle in the float isn't fully seating in the hole. You need to take the float bowl off, take the needle and float off, and spray air or carb cleaner through hole where the float needle goes.

Are the vent hoses always positioned above the carb like that?? If so that’s why, the drains have to be lower than the fuel level otherwise it gets all fucked up.

Normally the hoses drop below the carb .

You can see a metal tab on one hose that should be mounted with one of the bowl screws .

Yea either leave the hoses off or let them hang down.

I would leave the hoses on , as they act as a lineal 'filter' , helping to keep

any debris from getting inside the carb . ;)

Is the float needle sealing? A bad needle and seat will allow the carb to overflow.

The needle is brand new so i don't think that the problem. I have hade the carbertater fore only a cupol months so everthing is new.

100% is the needle. my bet is that you didn't install it correctly on the float when you put it back together. no biggie, happens to everyone.

carbs are really mechanically simple, so the float needle is pretty much the only thing it could be, it's really the only thing that controls flow to the carburetor

Re: my dt50mx carbeter is poring out bensin from a hoal from the carberater

with the carb off, float bowl basin off. u can test by holding carb upside down and blowing into fuel inlet, it should not let any air thru.

Re: my dt50mx carbeter is poring out bensin from a hoal from the carberater

Do these carbs have removable float seats?

Have you tested the carburetor while it was off the bike?

Re: my dt50mx carbeter is poring out bensin from a hoal from the carberater

I have seen more than one vm20 that are messed up from the factory.
