Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Welcome to JUST ANSWER small engines, let me try to help you !! I don't know it all, but maybe together we can get you a satisfactory answer!
When engine quits, do you have spark? With no spark, the coil is going bad, or the oil switch is killing the spark. Is oil level ok?
So when it quits it has spark? If you open the fule line at the carburetor , do you have fuel flowing? Fuel tanked venting, not drawing a vacuum on the tank?
Try it with loose fuel cap.
If a lack of fuel, that might be problem.
Sounds like fuel starvation from the tank to the carburetor. Tank line and filter all open going to the carb?
You said it had to sit a while before it would restart. That made me think you were loosing spark.
You said you have spark, when it quits, so that rules that out!
Yes, should be good spark! Maybe you do have bad coil.
With spark plug grounded, and hooked to the cable is the right way! It should have good bright spark at the tip of the plug.
!! Unplug the oil level sensor and see if it runs.
No , but will be on the crankcase of the engine.
I see question is still open, did you find problem?
