Onan spark plug
Simple question: What size socket is required to remove the spark plug from my gen set?
Forum Discussion
It's an Onan microquiet 4000. 5/8" is too small, 11/16" is too small, 3/4" is too small, 13/16" is too big ... Could it be metric? Perhaps I can get the heat shield off so I can see the whole plug. Access is a little awkward. This all stems from failure to start. It would start and run a few seconds, now it doesn't even try. It is getting a good spark from the wire terminal. The genset has only about 125 hours. Meanwhile, I'll check gas line. Thanks for your suggestions.
