Lawn tractor engine problem
Last year I bought a Murray lawn tractor with a 21hp B&S I/C engine.
Aside from the pulley housing on one of the blades disintegrating, it's been ok, not great (Murray reimbursed me for the repairs, but said that this was a "one-time" thing, not to expect them to honor the warranty every time - I'm serious!). Anyway, I've used the mower about 8-10 times to mow about 2+ acres over the past year, and last week just as I was finishing, the engine started surging and just before it quit, I pulled out the choke a bit and it started back up. I mowed for another 15 minutes and eventually had to pull the choke all the way out in order to keep the engine running. The mower doesn't run very fast in this mode, and doesn't have a lot of power. Any ideas what could be causing the problem? Checked the air filter and it's clean, as is the fuel filter - Thanks for any advice |

Lawn tractor engine problem
To tell the truth, I hadn't thought about bad gas, but that is a
possibility - or the gas could be dirty - I'll work on that this week and see what happens - thanks! On Tue, 8 Jul 2003 10:53:09 -0500, "Patch" wrote: "Steve" wrote in message .. .

Don't forget to check your air filter.

Remove the bowl from the carb and clean out the nut (which has a small hole) and the tube comming down from the carb body which usually has two holes with carb cleaner. |

Lawn tractor engine problem
Sam - thanks for the tip - I hadn't checked back here in a coupla
weeks. I did look at the carb, couldn't see any crud in it but didn't really know how to clean it (it didn't have a float, a very strange-looking device with just a little hole with a grommet in it). Anyway, I drained the tank and re-filled with gas and it still surged some, but eventually smoothed out quite a bit and I was able to do some mowing. I wonder if carb cleaner would hurt anything?
