Chinese stuff can be very bad, knocked out in a cottage somewhere. I have had problems of "concentricity" with round saw blades, (center hole not on center). Try putting the suspect units in a vise and turning the drive gear over while measuring for runout. If you don't have a dial indicator , try locking down a pointer of some kind from the base plate and judging the air gap to the shaft as it turns one revolution.

thanks i will give that a try but the last one i bought was from john deere which costs 300.00 and it didnt last any longer than the other one so i feel ive got another problem. i thought it could be the flywheel but it seems to be ok i may can rig up a pointer to the block and check it in the same manner. thanks great idea!!
