If it doesn't start after 5 or 6
pulls, there's something wrong with it and it needs to be fixed.

My old mower never used to start with less than half a dozen pulls.
When the old engine finally died - the valve seats fell out - I bought
a new Briggs & Stratton. When I get it out of the shed after the
winter it starts second pull. Every time after that till I put it
away it starts half way through the first pull. My dog could start
it.

Frankly, it continues to amaze me.
