it`s hard to start .it will not idle with choke off.
i`m thinking the exhaust valve ain`t closing tight.
auto parts stores don`t have service manuals.
china scooter store don`t work on them.
does anyone know clearances[cold]?

 

I looked online and found specs ranging from 0.003" to 0.005". I'd lean towards 0.005" and see if the valves are noisy; if so, I'd close them up to 0.004".

 

there is a valve clearance vid on tyoutube see if u can find it ill try also post a link if i do find it!

 

my compression guage don`t fit the little plug hole.i`ll try the rubber thing.
i`m guessing it should be around 90 lbs.
