Engine Warning Light Question
in General Tech Discussion
7 years ago
I'm looking for some help about my engine warning lamp. I went flying this morning. Stayed in the pattern doing touch and go's. I noticed that the engine warning light would come on whenever I pulled the throttle back to idle. The farther I pulled it back, the brighter it got. It has never come on like that before while the engine is running. The engine seemed to run smooth, no noticeable gaps in power.
Back on the ground, when I shut it down, it seemed to stop harder than normal. I started and stopped it several times and it seemed to jump pretty hard on startup and again stop harder than normal. I pulled the plane back in the hangar and pulled the prop thru several compression cycles while the engine was still hot. It was noticeably harder to pull the prop thru than normal.
After that I decided to pull some of the spark plugs and inspect them. The plugs on the left side were very black. The plugs on the right were light tan. I assume that means the left side is running rich? Is the whole problem due to the carbs being out of balance?
With the top plugs out and after the engine cooled for a bit, I pulled the prop thru a few more cycles. It pulled thru smoothly, no binding or unusual noises noticed.
Any ideas? Thanks!
