My son has been "lent" a chinese motorcross style mini bike.
The bike was bought in December and was ridden no more than a dozen times before arriving on our doorstep.
When we took it out for a ride we discovered it won't run for any length of time. It starts first pull, pulls away cleanly runs for a short time then cuts out, no warning, loss of power, misfiring or anything. It will also not idle no matter how much I fiddle with the cable adjustment or the idle screw on the carb.
At first I thought it was because the engine was cold, then because the young feller was being a bit gentle, but it does exactly the same thing no matter how you ride it-gently or flat out, hot or cold. It runs for a short time then dies.
I took the motor out, stripped the carb, which was full of fine grit, cleaned everything carefully, put it together and...it was exactly the same.
I cannot be beaten by something this simple, it is just not right!
Any suggestions would be appreciated. Thanks guys:rolleyes:
