Lawn boy 5236 won't start repeatedly
I have a lawnboy mower 5236 which is giving me trouble starting. At times, it fires up without issues and then refuses to start when I switch it off.
I have already replaced the spark plug and plug wire. It bears mentioning that the mower has been lying idle for 10 years or so.
It doesn't have the ON/OFF knob but it starts all the same. When starting it, I first prime it for about 10 times and then pull the cord. Sometimes it sputters for a minute or two and then starts and runs like it's new. At other times, it completely refuses to start.
What could be the problem?
