X6 150cc carb problem

Having abit of troube with the carb. It idles perfect with the lever up but dies when throttling. No matter how much i adjust air and fuel it's still the same but gets better. When i have the lever down it has higher idle and can throttle propely with out dieing. Is this something with air leakage or not getting thru enough air? I'm not sure which way the choke is on or off.

First parts of the vidoes are recently and last part is from last summer before old carb broke down

Both carbs are PZ19 Older one was made in Japan, the new one China.

Re: X6 150cc carb problem

I think your too lean, that carb is to small for a 150cc engine, you could probably run up to a 30mm carb. The PZ19 was to small for my 110cc X18 for hp riding. The sign is, it run better with the choke on. The choke plate blocks the airflow in the front of the carb, and it has its own passageway to the float bowl gas which it draws when the choke is or more gas to the engine, you can try to put a bigger main jet.

Re: X6 150cc carb problem

Weird part is that it ran very good with my old PZ19 that was made in japan i even had wrong adjustments on the air/fuel mixture and with idle too!

Even with your old carb the jets might have been bigger. Motor still had to be running lean. I would go with a 26mm carb to be on the safe side.
Like epr said the 19mm is to small.

Re: X6 150cc carb problem

if you have to have the choke on, it getting too much air or not enough gas
either way making a lean condition which is worse than running rich
lean makes more heat and power but risky to overheat
I like to dial my stuff in by going very rich and then dialing back

Re: X6 150cc carb problem

because when you throttle you get way more air than gas and it dies
you need to find out why the gas is lacking
are the lines from the tank good and flowing, is the gas getting in the carb bowl (there is usually a screw at the bottom you can open and see if gas comes out), are any of the jets got crap in them, even new carbs can get stuff, is there a air leak at the carb manifold?
lots of things to verify

Re: X6 150cc carb problem

Sorry for late respond as i havn't had any time to work on it as it has been cold outside, I finally got it to start by changing jets recently and didn't care about the gasket between carb and the intake. Runs alot better then before and sounds even nicer A quick video of it running and also a old picture if anyone wants to see how it looked like before (2010, basically the same as today just less rust)

Re: X6 150cc carb problem

I have a brand new PZ27mm carb, that's the carb the 150cc comes with, sell it for $25 shipped. Might have an intake manifold that fits also. The height and the shape of the intake need to be right to fit into the frame an clear everything. You can use an $8 alum carb swivel, see gold circle under the intake manifold.
