Yamaha aerox R 50cc

Hello guys,
Recently i tried to install a new carburettor on my yamaha aerox r50 cc 2017
The name of carburetor is "carburetor Dellorto PHVA 17.5 TS" all good al the pipes are plugged as they should be. The carburettor didn't come with electric Cooke and i used from old carburetor. But pointless i try to start the engine and nothing is sound like tries to star but nothing.
I put back the old carburetor and is working perfectly fine.
I don't know what to do more. I'm planning to buy a manual cooke to inserted instead of electric one to see if will work. But before to buy i need some advices. Please can someone help me?
I will attach the pictures of carburetor and cooke.
Thank you.

 

Hi Teodor, is the fuel actually coming though? You might need to give the jet a good clean.

 

Yes the fuel is coming, i can see some gas in carburettor. Actually when i put back the old carburetor is working straight away.
But with new one no way to start.
Thank you for replying.

 

No worries, and how annoying is that. I'll keep on scratching my head.

 

Is really strange, i don't get it why i have this issue.

 

Hmmmm....
Is there any fuel getting to the carburettor?

 

Yes, is coming becaus3 when i take it out he had a bit of gas inside. But what i realise the oil pipe i tried to blow the oil out and is going so hard.
I will try again in next weekend to see if i can do something.
I just want to make it work

 

Hello guy, i would like to let u know ai solved the problem,
To start the engine with new carburettor i just add a bit of gas on the carburetor and is working perfectly fine. Maybe some of you will have the same problem and you can try like me.
Another problem i have with my scooter is when the engine is cold and i switch on the engine the rear wheel start to spinning like a crazy after a while is stops and is working fine.
Could you guys please give me some advice regarding my problem.
Thank you.

 

Simple solution, good work!
What's the tickover/idle speed when you start it up? I mean how many revs is it turning over?

 

Thank you
The think is i can't see any revs on scooyer watch.
And the think is just when is cd the engine the rear wheel is spinning very fast and then when get hot the idle is like should be.
The problem is just when is cold

 

That's the automatic choke doing it's thing

 

And how i can fix it to stop doing this?

 

Hey guys can someone please help me iwould like to try again to fix it today after work and i cannot find nothing on Internet....
Thank you

 

When you say spins like crazy how fast are we talking about. I mean mine spins a bit till the engine's warm but that's normal.

 

All bikes do that.
There is nothing to fix

 

Ok i get it, anyway i think i adjusted bad the carburettor i will try again today and i will come with an update.
I know when the engine is cold will be like this but i think is to fast i will try to adjusted and then we will see.
Thank you guys
