taotao 50cc new carburetor has no accelerator pump By dougar48 (Read 7,018 times)

I received a new carburetor the other day that I ordered from ebay. It is a KEI HIN CVK carburetor. When I opened it up I noticed that it did not have an accelerator pump. The casting did not have the location for the pump completed and no pump which seemed rather odd. Do you know what is going on Will this carb function on my 2011 TaoTao 50cc scooter?

Yes it will work just fine, there are two kinds of carbs ones that come with a pump and ones that do not have a pump. The ones with a pump sometimes cause troubles because if you twist the throttle enough it squirts more fuel into the venturi.

All right! I thought as much but wanted to hear about it from someone that knows.
Thanks Alleyoop! I'm new to this forum and this was my first post. This is a very cool site.

I just got a new carb without a accelerator pump, how do I switch from my old one to the new?

[markwb]

Remove old carb, install new carb, no further action required except maybe some minor tweeks.

I put the new carb on and got nothing

[redroush00]

Prime the fuel. Takes awhile if you have a petcock

[Alleyoop]

If the carb is a CVK carb and it does not have an accelerator pump, IT has a ACV valve that requires VACUUM.
Here is what your carb looks like without a pump, NOTICE you need a Vacuum hose going to the ACV valve.

Here is MY OWN CARB connections:

Yeah! My carb looks just like that.
So I hook the vacuum up to the mani and use a t for the fuel pump.
Is that correct?

[Alleyoop]

If you used a "T" then hook it up like mine is.

I'll do that tomorrow.
Thanks! I'll let u know how it works

[mojo50100]

Thanks! It works, only problem is sometimes when I try to start it I need to prime it.
I think maybe a bigger jet or lines, what do you think?

[Alleyoop]

Great, No you just have to adjust the carbs Fuel Ratio Mixture.
