Mechanical help needed - poor starting and running

[casper]

Hi crazy carl,
Thanks very much for your reply.
I understand everything that you say , but what's got me baffled is that it does get better and stops cutting out after a time , so if it was an air leak it would surely not improve with time but do it all the time.It does have a lack of power all the time.
The plug has been replaced.
After they striped & cleaned the carb & tank it did stop cutting out for a short time but still did not have it's normal power , this did not last long & it reverted back to cutting out after a day or so.
It is a lesson in frustration as I cannot speak Chinese and I don't know if my wife translates what I am trying to say correctly.
These road side repair people have no testing equipment at all & I just know they don't know what they are doing,but I also they are just trying to earn a living so I can't be too hard on them.
I will disconnect the auto choke as this reacts from the heat of the engine & maybe the mixture is wrong this is why it never has no power.
Any more thoughts from you ?
I will let you know how I get on.
Regards Casper.

It ain't necessarily so. If it's an air leak and has to do with rubber, it will expand as it heats. Either way, it shouldn't be so bad that the scoot will stop running.

My wife and I had a Jialing 50 cc scooter in Chengdu before we left and it had all kinds of weird problems running and starting which ended up being a problem with the front variator. I would check inside the drive case and make sure the belts and pulley are all okay.
