Yesterday I encountered the ongoing problem of our push mower refusing to re-start after it gets hot. We are already behind on the mowing, since we waited several days for a replacement primer bulb to come in the mail last week. Apparently the hot-start problem is very common in 7- to 10-year-old Briggs & Stratton engines. It can be caused by issues with the valves, the coil, or a plethora of other things – in other words, a two or three day troubleshooting process for a shade tree mechanic like myself. In other words, not something I have time to tackle right now.
I don’t think it’s a compression problem in our case, as you can clearly feel the compression stroke when pulling the starter rope. A common bit of advice on internet forums suggests solving this problem by sitting in the shade with your mower while downing a couple of beers (the beer is for you, not the mower, silly), and then starting it again after it’s cooled down.
I put the mower in the shade and spent about 20 minutes reading up on the problem online. No beer, unfortunately, as I was trying to get this done and get out the door to hike. The shade definitely shortens the refractory period, and it started right up when I was done reading. In the end, I did get the dry grass cut at the top of the hill, so I will no longer get foxtails down my boots when I go troubleshoot the soaker hoses on the caragana hedge.
