Tried mowing the lawn this weekend. It would run for a while and then sort of backfire a bit then die. One pull, starts back up, mow for a bit then dies again. Any ideas of what the problem might be?
Thanks, Rob |

old winter fuel? sounds like it's starving. it's probably got no filter and may have caught a chunk-o-crap inroute to the carb. if you ever run it low, sometimes it'l plug

Last year, my mower had a similar problem. I blew carb cleaner and compressed air through the carb passages and it helped. This year, not so much. I rebuilt the carb and now it starts on the first pull (as long as I use the priming bulb before starting).

Cracked priming bulb, plugged carb, old gas. If your lucky once you get that fixed your coil won't go out like mine did. Hopefully not a Tecumseh motor. No parts for them any longer.

Thanks for the suggestions guys!! No priming buld on this mower. Will take the carb apart and clean clean clean... the culprits got to be with the float. Will also check for a plugged fuel cap.

Check the ground strap between the tranny and the body.

I always run the lawn mower and snow blower dry. I'm betting old fuel too. Most carbs have drains on the bottom of the bowl. There will be a spring on a needle type valve. Press up and it'll drain. Drain it out and give new fuel a shot. If that doesn't work unscrew the bowl and clean it out along with the passages.

My mower runs better than my 914 and turns a whole lot sharper. It's like riding a cutting horse.

@Charlie: Zero turn?
My main mower is a 1970 John Deere 140 with Kohler K321 engine. I can't keep a head gasket on it... seriously thinking of repowering it with a Briggs @ Stratton 18 HP V-Twin. |

My '84 JD 111 sat for a couple of years in the driveway, partially disassembled, before I finally sold it on Craigslist. This one's a keeper so I will probably want to wait until summer, when I won't have to mow as much. For now I've got a stack of head gaskets and probably a spare head. |
