1941 Farmall BN Runs Bad

I am back again looking for help with this BN. I started the BN and could tell it was missing. I heard only two cylinders working.I verified all four cylinders had spark. When I pulled the plugs back out, two were wet and two were dry. I am wondering if maybe two cylinders have valve problems, maybe the seats are bad and are allowing too much fuel to enter the cylinder. Does this sound right? Could it be a carb issue? Give me what you got.........

First check the wires make sure they are in the rite order on the cap. Next check the valve clearence. Then take the two that are firing and replace them with the wet ones. If they get wet you have a valve problem.

You may want to do a compression test that will tell you about valves rings etc. checking to be sure the SP wires are right is also a great idea.

Also an easier one is to take off the valve cover when you've exhausted (no pun) normal troubleshooting.

You can visualize the action of the valves and make sure all pushrods are seated and none bent.

Where can I find the proper firing order of the cap? Do I have to buy a manual for the tractor?

I compared the spark plug wire orientation to my '47 B and things look good there. I am wondering if this is a timing issue. How can I adjust the timing?

Hi, timing won't effect 2 cylinder only, here's a handy tool to check if your getting spark on all wires, a compression test is still a good option on the dead cylinders. The firing order is on the engine and # 1 is marked on the dist. cap so figuring that out is simple enough, do you have a full 6 volts at the coil / dist?

These are very easy to use and are handy.

The firing order is stamped on the block in front of the filter 1342 with #1 on the cap at around the 1 oclock position looking from the rear and facing towards the radiator. The rotor turns clockwise. Remove the #1 plug take the cap off the mag. Using the crank turn the engine over till the rotor points to the #1 position you can see when the piston comes to the top with a flashlite. Turning the crank more the rotor will snap. Turning the crank more the rotor will advance to the next position and stop you can remove #3 sparkplug turning engine slow till you see the piston come up. The rotor will now be at the 4 oclock position. Turning engine slow you will again hear and see the mag snap when #3 gets to the top. You mite want to remove all the plugs before turning the engine over it will make turning with the crank easier. I am assuiming that you havent removed the mag or have replaced the points. If you have the wires in their correct position on the cap and going to the correct plug your engine should run. If not give me a call 319-430-3907 and i can walk you thru it again. I use a small mag lite to look into the cycls but a flaslite will also work. good luck.
