I have a Toro Recycler Mower with a "Guaranteed To Start"
engine. The mower is self-propelled with an electric
start and is about a year and a half old.

It is very difficult to start the mower the first time,
either by electric start or by pulling the cord. Once
I get it started the first time, it is no problem to
restart after emptying the bag.

Does anyone have any suggestions on what might be the
culprit?

Thanks very much.
