Testing electric choke on my Baotian 4 stroke GY6 and adjusting air fuel screw and starting it

The scooter is running bad when cold, does not respond on throttle until it get warm. When it's warm it works as it should.
I decide to remove the electric choke from a PD18J carburetor and see if it works.
Also tries to adjust the air/fuel screw and see if it makes any difference between 1.5 and 2 turns out.
I hook the electric choke to a 12V battery.

So when u first start the choke is open allowing fuel and air, and when it warms the choke extends limiting fuel and air is that right?

Yes, that's how I interpret it too.

[@Stefffeh]

It only limits fuel when its out :)

Hi, did you find the cause? I have a very similar problem on a speedfight 4. Starts and idles just fine, but can't throttle until it's had a minute or it will just bog down. Starts and runs great when warm...

Hi! No, got it working for a while but then had problems again (just cleaning the carb). I got tired of the carburetor and have changed to a slide carburetor pz19. Video will hopefully come after summer / winter.

@@ScooterSimplicity Thanks! I managed to solve it. The fuel mix was simply too rich. Some grit in the fuel mix screw gave it a false bottom and what I believed to be 1.5 turns was something else!

Thats normal as well, any vehicle that works with a carburetor has to be warm before riding/driving. If you start it and try to take off right away it will bug out

I changed the main jet and did a valve adjustment it made mine stop doing that

[@whatisdreup2]

Thats normal, your choke is working properly. When is cold is letting more fuel through (running rich) until the engine gets warm. when is warm is on the close position. You said when is warm is runs good. So there was no need to do all this
