I've got a Massey 35 (3 cylinder) that is hard to start, bogs down easily and exhaust huge amounts of black smoke. From what I've been able to glean in research, this is likely and fuel/air issue.
I changed both fuel filters, removed and had tested the injectors, one turned out to be faulty. Still bogging down and black smoke.
I removed the complete air cleaner and ran the tractor for about an hour. Really did not notice a difference in smoke, however, I did notice that where the rubber hose to the cleaner would normally be attached to the engine (next to the preheat starter element), that there was an exhaust coming from there and that when the engine would bog down (as it often does) I could see combustion (flames), almost like looking into a furnace. Is this normal?
If it is indeed a fuel/air issue, is it perhaps the fuel pump?
Any advice thoughts are much appreciated.
