Hi all,
I have an MTD RL638 riding mower. Recently it is very stubborn to start.
I replaced the lower bowl of the carb, installed new fuel filter and spark plug. Still wouldn't start.
Took it to a local small engine shop and the tech wrote on the invoice that the "carb was airlocked. cleared air lock and it started right up"
That was about 6 weeks ago. Now, it's acting up again.
The majority of the information I was able to get off Google searches is about vapor lock.
Is vapor lock and air lock the same? If not, how do I clear the air lock and how do I prevent it from recurring?
Many thanks in advance to all that assist.
Picture of the setup can be seen at this link:
