Either jet would be OK probably... but the #105 may be big.. usually 150ccs use a #103 to #105
125cc would likely use a smaller jet.. best way is to try them...but if the original was a #95 then use that jet in the new carb...

ok, i'll try and see.
What are the symptoms of lean or rich mixture?
If the engine RPM going up good, but the engine power feel a little low,
is it a rich or lean mixture?
Thank you.

a quick way to get it in the ball park is to run up throttle on the stand with your hand slightly choking carb. If it runs better with a bit of choke the jet needs to be bigger, if it runs worse the jet could maybe be a bit smaller.

Well it depends on the temp outside, if the temps are cold it is most likely to lean if the temps are hot it is most likely to rich.
