I recently picked up a small mower on craigslist as a fun side-project, but I have had only a little experience with small engines, and limited limited funds for troubleshooting.
Could someone give me their thoughts/comments on my thinking?
Here's what I know:
- Spark plug was wet when I inspected it but has spark after changing it.
- I don't smell any combustion
- Gas might be a bit old (6-months to a year)
My conclusions / assumptions:
If spark plug is wet, this may rule out carb issues (please verify this logic).
If spark and fuel exist, this can only mean a weak spark (please verify this logic)
Before I buy an ignition coil or a tester, can someone help me understand anything else I may need to test or rule out?
Update: Upon further inspection, I discovered more. What seemed like dirt was actually a significant amount of oil buildup around the circumference of where the motor attaches to the body of the mower. I'm guessing oil leaks are bad news?
