I am working on a 3010 gas, it would not start and gas was constantly dripping out of the carburetor. The owner had been complaining of poor operation recently. The tractor has a history of dirt blocking the fuel path from the tank. (Compressed air blown backwards from the lift pump to the tank cleared the block.) A fuel line filter had been added about a year ago. This spring it seemed to start and run OK, opening the fuel jet made it run better. The tractor was used for raking hay this summer. As I said, operation had degraded recently. At the last shutdown the owner said there were flames coming from the exhaust that were actually a little hard to extinguish. I believe he also mentioned backfire. I need to confirm that as it may be important to what I am seeing.
OK, that is some background. Here are some actions and a question.
1. I sent the carburetor to Robert's Carburetor. It had a film of sooty material lining the entire inside, at least as much as I could see. I did not take it apart. Roberts acknowledged they got it.
2. From my initial call Roberts wanted me to do a compressor test and test the plugs, points, and wires, which I will do.
3. Today I removed the hood, the coil states there should be an external resistor, I cannot find it. Where should it be? I ordered a service manual but my 2510 manual shows it between the coil and the common node between the alternator and the dash light.
4. I observed the air cleaner has oil all over its intake and the side of the canister. See Pictures. Why might this be??? Oil level is correct. I removed the pipe leading from the air cleaner to the carburetor, the inlet to the pipe (leaving the air cleaner) is very clean. This surprised me, I thought I would see oil. The exit of the pipe leading to he carburetor is covered with the same sooty/oil material I found in the carburetor.
5. So maybe I answered my own question, perhaps a bad backfire pushed the oil out of the air cleaner. Is this possible?? There is enough dust on the oil it does not appear to be entirely recent.
Comments? Why would oil back out of the oil bath air cleaner? Any other comments as to what to look for. I am anxious to do a compression test now.
By the way, shining a light in the gas tank shows a nice clean silvery bottom. I did see a wire, a couple un-identifiable small dirt particles, and a kernel of corn.
