I run this mower and it has less than 50 hours on it. It has been hard to start from day one. It takes atleast 5-6 pulls after priming. It has a 6.75 HP OHV Briggs on it. Myabe this is normal for this type of engine, but my lower grade MTD's start on the very first pull Also, it takes 5-6 hard, quick pulls not weenie pulls.
