Hi everyone. I'm new to this forum. I have lots of
experience with automotive repair but none with
tractors. I recently purchased a massey harris 50
with the continental z-134 gas engine. The tractor
did not start or run when I got it. I was told it
ran when parked 2 years ago but after parking it the
previous owner was never able to get it re started.
I changed the oil, drained the gas, replaced the
ignition switch (the old 1 was broken), repaired
several broken wires and replaced the plugs. The
tractor now starts right up and runs. It idles fine
and sounds ok, but above idle it has a knocking
noise which sounds like it is coming from the front
of the engine. The knocking gets worse with engine
rpm. When I removed the oil filter I noticed gray
sludge inside the metal canister. Water? Metal? I
dont know for sure. It didn't feel too gritty. Also
the engine speed will gradually increase on its own.
The hole in the dash for the throttle lever is worn
and the shaft is very loose. When the lever is
pushed all the way up, idle, it comes back down a
little. Is there some kind of bushing that is
missing, or is the hole just worn? Is this a linkage
adjustment? Is this a governor issue? I have a
repair manual on the way. I know I have asked
several questions here and this tractor has several
possible problems. Is the knocking, and
governor/idle issue related? What should I
check/take apart first? I can provide more detailed
information if necessary. Any thoughts and help
would be greatly apreciated. Thanks
