- From CVK carburetor PD18J to PZ19 Carburetor
on Baotian Sprint & Testdrive
Testing diffrent main jets and Also replace Throttle Cable)
PD18J is of type constant velocity carburetors and uses Vacuum to pull throttle.
Slide carburetor or flatslite (I think) is more simple. PZ19 does not have accelerator pump for example.
PZ19 is 19mm (widest opening) and I bought the version with Cable Choke.
Simple 35mm Air Filter and Universal 20mm Intake manifold
139QMA engine code
Replacing throttle wire / cable to a one that fits PZ19
PD18J has vacuum operated slide (throttlebody) that changes the diameter of the main opening. In the carburetor there is something called a venturi, it narrows the intake to create a "venturi effect" which changes the pressure of both sides of the carburetor.
Changes from CVK to PZ19 slide carburettor and thus leaves vacuum controlled carburettor for something simpler. Scooter is Baotian or BTM BT49QT-12, 50cc Moped
In this video I test a few different intakes and change the main nozzle and adjust the needle so that the moped does not "bog down"
After all the problems I had with the original carburettor PD18J, I am now happy that the scooter works to use. I also bought another intake which I might test in a future video. Don't forget to check out my other scooter videos.

Byter från CVK till PZ19 slid förgasare och lämnar därmed vakuumstyrd förgasare för något enklare.
I denna video testar jag lite olika insug samt byter huvudmunstycke och ställer om nålen för att mopeden inte ska "bog down"
Efter alla problem jag haft med orginalförgasaren PD18J är jag nu glad att mopeden fungerar att använda. Jag har även köpt ett annat insug som jag kanske testar i en framtida video. Glöm inte att kolla in mina andra scooter videos.
