Well, I'm no Briggs expert, but I'm wondering if the spark is inconsistent or weak. Have you checked the gap? Also, you might try taking the plug out but leaving the wire on it, lashing the base to something grounded, using bare wire, and then turn it over while looking to see how bright the spark is.

I suspect these no longer use a magneto and/or points, which they did when I learned about them, so I won't try to guess what else might be wrong with the ignition. Still, it would be very quick to check for loose wires, condition of the spark plug wire, etc. I guess most of them are probably under the flywheel, though.

I'm just mentioning the above because they are easy to check. Might as well do that stuff first. I guess it's just as possible the mixture is off or something, but that's more work.

17.5 hp briggs and stratton mower - mowing fine - stopped to gas up - will not start back up - back fires a few times while turning motor over


sounds like you may have a broken valve spring. Do a compression test as you crank it. If the valve spring is broken, you will get nearly zero compression, it will turn over very easily and this would explain a couple of backfires.

Briggs and Stratton 20 hp intek runs great idles great but after running for 15 min. it acts like is running out of fuel and dies. it starts back up if you wait a few min.fuel filter new , plugs new air...


Had the same problem with an almost new Craftsman w/ Intek 20.0 HP. Check all the "usual suspects" and had to have a tech come out. He had me start it. It ran for a few minutes and stopped (per usual). He immediately went to the Anti-Backfire solenoid. It is an electrically operated "plunger-style" fuel line blocker. They are famous for going bad. The part is about $65 and its sole purpose is to starve the engine of its fuel supply at shutdown so it won't backfire. If it is disabled, the user must throttle the engine down for 10 seconds or so before turning the key off in order to avoid backfires. Gee... let's see, 10 seconds of my time each time I use the mower vs $65 part ... No contest! Remove the solenoid, take a pair of electrician side cutters and snip off the tip of the plunger and reinstall it. Problem solved ! ! !

B&S engine backfires, runs better with choke 1/2 out under load??


Check your rockers inside valve covers. They some time work loose. If they are loose the push rod will fall off rocker and cause the problem.
