This is the second one, from Lowes.  Acts just like the original; pulls hard, because your turning the heavy flywheel, with the shredder attachments.  I've tried pulling, as many as 18-20 times, with no results.  At times it will start, after 2-3 attempts.  When running, it surely does the job.  When I shut it down to refuel & check the oil, it won't restart.  Have to wait, sometimes for 1/2 hr.  After purchase, I started reading reviews on the Lowes site. One of the problems, is the hard starting & havi9ng to wait for a restart.  My next step, is the starting fluid.  
Thanks for your help.
