Low oil, runs a second or two then dies
I am working on a walk-behind mower with a Tecumseh engine. The mower will start with starter fluid and run strong for two seconds and then die. I cleaned the carb and replaced the primer bulb. Same problem.
The owner had run it nearly out of oil. It took 16 oz. to get it back to full.
I am wondering if I should keep looking for a carb problem or if the low oil ruined the engine. I am not sure if a ruined engine would even start at all. It runs good and strong for the two seconds that it runs.
