after almost 15 tanks my NS12 S3 is still hard to fire up, piston still tight. guess i need to add few more tanks before it get less tight.

anyway, i find there is "freeplay" where the cranksahaft moves horizontally in and out after i install the cone+flywheel ( this before i started to break in process) ,i have tried a few times to reinstall but still the same is this normal or factory defects. but it idle and run normal.
thanks
