Cool Hard to start my Huasheng

It takes about 15-20 pulls to cold start my Huasheng engine with the choke, once its running it runs great.

Brand new NGK plug.
Fresh 87 octane gas
I did a recent Valve adjustment but that made no difference.

Im confused why she is so difficult to start...

I never had one of these yet am waiting to buy my 49cc!

Try 1-2 pulls full choke, then try moving it. Even harder to start? Might be your carb

How did your old plug look? Lean?

check your carb,,,the jets are known for getting clogged easily,,,especially if ethanol is in the gas

I am with Bill - clean the slow jet on the carb. Here's a video from Dax on how to do it:

Smile I appreciate the help.

Okay thanks everyone when i get back from my vacation i will look into the carburetor. I live in CA so i have to deal with the (E10) Oxygenated gasoline.


Its mounted in the center of a 26 inch beach cruiser.

Spark plug is golden brown and i jetted the main jet to 0.74 because with 0.73 it bogged really badly.

I have the same problem but am too lazy to take the carb off to clean the jets. But to overcome the problem I just spray a shot of carb cleaner into the carb and the engine starts immedately.

No difference. Still 15-20 pulls. Its very annoying.

There is no need to remove the carburetor to clean the slow speed jet.
See "Titan Slow Jet Cleaning" on DAX's site. The Titan and the HuaSheng have the same carburetor.
Here: http://thatsdax.com/INSTALL_AND_SERV...OS_PAGE_2.html

If that jet has even the teeniest little bit of crap stuck in it the engine will be hard to start.
