I know nothing about lawn mowers?

Question

i have a lawn mower that will start but wont stay running can anyone help me?

Answer 1

You can get some seafoam or B12 at an auto parts store and add it to your gas since you have probably never cleaned the carb. passages.Else rebuild the carb.

Answer 2

Try leaving it alone for a while. If you live in a warm area such as Florida, it may have overheated, and needs to cool.

Answer 3

It would be a lot easier to help you if you said what size and brand of engine.  In any case it is the carburetor.  It needs to be cleaned and a rebuild kit installed.  It has to be cleaned good.  All passages clear etc.  Make sure that the fuel tank is clean also.  

Answer 4

Arron change out the spark plug.

Good Luck
