It sounds the same as when the tank is run dry. There are no numbers under the plastic cover, so not sure what others you might need (both the engine serial number and type are there.)
HarmoneySeeker, it does not make a difference, even if you take the cap completely off.
My B&S lawnmower starts when I add starter fluid or prime for a while, then dies. I have cleaned out the ENTIRE carb, checked the gas and its filter, but nothing helps. Any ideas why or how to fix it?
Thanks
