I just bought my first tractor two weeks ago. Everything worked great until yesterday. After firing it up I noticed a lack of power. At full acceleration it barely moved. I then noticed oil coming out of the exhaust manifold where the manifold connects to the exhaust pipe. Does anyone have any suggestions to what the problem may be? Thank you.

 Revised Compression #'s in reply to Robert Shefferly III, 02-27-2005 08:03:39  
After reading something on this website I realized I performed the compression check worng. The number provided previously were the first jump of the needle. The revised numbers are as follows: #1 120, #2 105, #3 130, #4 120. The excerpt I read stated it should be done when the motoer is warmed up, but that is not possible in my situation. So the above numbers are cold numbers. I do not know what the effect is on the numbers above if the motor was warm. Thank you for your help.

check your oil in the pan might be full of gas

Thank you for your response, I did what you said with no luck. The spark plugs were out of gap so I adjusted them. It is clearly oil that is coming out. I looked into the hole where the spark plug goes into and cylinder numbers 1, 2, and 3 all had a black wet appearance to them and #4 looked dry. Similarly the spark plugs for 1, 2, and 3 were all fouled up with oil and #4 was dry. The plugs appear to be relatively new. The fuel in the tank is all new. I checked the continuity of the spark plug wires and they all checked out. The cap and rotar also look relatively new and do not have any corrosion on them.

Have you tried the compression on all cylinders, turning it over on the handle it should be springy when you do, if the compression is down on any cylinders it will need the valves grinding in. Turning it on the starter with fully charged battery you should get a pressure of about 100psi if you use a compression tester. Have you got the correct plugs for the engine, Champion L10 or NGK B6HS set to .030". Is the distributor cap cracked around the centre HT lead, is the rotor arm cracked. Is there wear in the distributor shaft allowing side movement to open and close the points gap as it runs. Any fuel in the bore will be unburnt and give the impression of oil but it isnt always. you could also check the valve clearances before you strip it down if any compresions are low. inlet .010" exhaust .012" all cold. Is the top of the coil cracked. is the condenser playing up, try another.Compression is main thing to get it going, if it isnt right then the head will have to come off and investigate further, it could be just valves you may have to check rings too. Try all this and then email me at:- fergusontractors at tiscali dot co dot uk
and we can go deeper into it.

John,

I sent you an e-mail as well, not sure if you received it. Here are the results of the compression check: #1 90, #2 65, #3 90, #4 90. I am in the process of locating the other parts at a place that has them in stock. Thank you for your help.

From what you say it is probably not firing on all cylinders and that "oil" coming from the exhaust will probably be unburnt fuel. Clean the plugs for a start and make sure they are dry and the gap is set to .030" and then you can try again. The fuel may have gone off too if it has been lying around with fuel in the tank, try draining some out and smelling it, it should smell like gasoline and not like paint thinners.Try some fresh fuel in the tank, drain the old stuff out first. When you have done all this and tried it if you are still in trouble mail again please.
