Honda FG110A Tiller Problem
My FG110 A Honda mini-tiller has a problem that I need help diagnosing.
Every time I start tilling it runs great at full throttle for 8-10 minutes. Then, with the throttle wide open, it begins to slow down. I have to let up on the throttle to keep it running, "goosing" it, and even with that it won't go back to full speed. If I let go the throttle, it dies. But starts right up immediately, first pull, every time.
Here is what I have replaced:
All fuel lines and tank filter
Gasoline (running non-ethanol gas)
Cleaned muffler to assure no blockage
Checked valve clearance (for fun)
I cannot think what else there is on this tiny unit, but to have it quit after 8 minutes is just horrible. I have a huge garden with a lot of clay so I have to run the thing wide open most of the time. This problem did not occur until after I had about 80 hours on it.
Any ideas will be greatly appreciated!
