New battery, but won't start. It makes a quick short attempt to turn then stops. Can anyone help?
Posting the Sears 917.xxxxxx number or engine Brand, Model & Type/Spec would be useful.
IF this is a Briggs OHV engine, the valves must be adjusted correctly for the compression release to work.
You may have a new battery, but is it GOOD? Is it Charged?
New ones are bad far too often.
