Yesterday I started my T140 for the first time after rebuilding the engine this winter. It started on the second kick and everything sounded good. I watched and waited for the oil return to the tank after 30-40 seconds with not even a spurt of oil, I shut down the engine.
At this point I noticed that the oil level in the tank had dropped considerably, so I pulled the sump plug and out came 16oz of oil, previous to starting the engine I had added about 4 oz. to the sump. It was obvious that the pump was feeding, but not returning the oil.
After removal and inspection the pump, it appears to be in working order. I have also confirmed that the oil lines are installed properly. What could be the problem?
