Briggs & Stratton engine has no spark

Hi

I have a small push mower with a Briggs & Stratton engine (engine number 09D902 2054 B1 07030121). It worked fine a couple of weeks ago, but it now won't start at all.

I've sprayed carb cleaner in the carb and tank and added fresh treated fuel and checked the air filter.

The blades turn when pull the cord, but I don't appear to have a spark, even though I fitted a new plug yesterday. (Removed plug and re-attached lead and held against bare metal surface while pulling cord, but could not see a spark)

I've searched all over, but can't find what to try next.

Any help greatly appreciated

Remove the kill wire from the coil and check for spark again, if none then the coil needs replacing.

Usually no spark on a walk behind is caused by the cable that connects to the dead man bar not pulling the switch far enough. If you find there is spark with the kill wire removed, you probably need a new kill cable.

Thanks for the quick replies. I tried removing the wire and still had no spark.

It looks like it's a stretched cable. If I pull the inner cable while holding the bar and pulling the rope, it will start!

Yep, sounds like your cable is stretched...
