Today I was cutting the lawn and 20 min into it, while stationary on level ground, it just stopped running, like it ran out of fuel. Tank was 2/3 full though! It did this 2 weeks ago but since it was close to being out of fuel, I figured that was the cause. It also fits with another symptom I've noticed over the past several mows, the mower is not quickly getting up to running rpm once it starts. It barely turns over, then over the next 3-5 seconds it sputters up to speed, then acts fully normal. For the past 2 years this Poulon Pro mower has run fine without any of these symptoms. It's 2 years old now and still on all original parts and filters.
B&S 126 cc engine. No choke. Primer button only. Fuel is about 6 weeks old. Considering I've run this mower fine on 6 month old fuel several times in the past, I don't think it's the fuel. This same fuel was fine 4 weeks ago. Another "issue" is that I'm pretty certain the "control run/start bar" has changed position a bit. It doesn't seem to get any resistance until it's almost fully depressed. It didn't feel like that a month ago. Still, it starts and stops via this lever w/o a problem. I don't think that's related to the stopping issue. Been running a little bit of Techron on every fill up this season to help keep the carb clean.
So what are the MOST often seen causes the would shut down the mower after running perfectly fine for 20-30 min, once it gets hot? It will restart, but only run 1 minute the next time, and 5-20 seconds after that. Here are some things I found on line to check - though I've never had any issue on any of these. Never changed them either, never needed to. Change oil...clean air filter...fresh gas...and go.
Spark plug? Clogged gas cap vent? Too much oil? (no, it's just right) Clogged air filter? (not likely, but I washed it very thoroughly anyways for the next attempt). Carb (air/fuel ratio)? Anything else?
This is a first for me. I've had these little inexpensive gas mowers for 20 yrs and the only failure mode in the past has been hard starting to no starting. Any help would be appreciated. Not a fan of pulling apart the carb as the last time I did that, the mower never even started again.
