Hi all, I put my AC-C back together Sunday and it doesn't seem to be leaking any water. But now my problem seems to be in ignition. When I try to start the tractor I get kinda a pop sound and then fire out of the exhaust pipe. What would cause this? Is it timing or do I have my spark plugs in the wrong spot? And also, how do you tell where to put the plug wires coming out of the mag cap? Thanks, TractorMike

On my Fairbanks-Morse mag, #1 plug wire is top left, #2 is top right, #3 is bottom left, #4 is bottom right. This is looking at the cap from rear of tractor. Firing order is 1243. Mag should be timed to fire #1 on compression stroke of front cyl. and flywheel mark TDC in the round hole on left side of bell-housing.

Tractor Mike, I have a "C" and as you sit in the seat looking forward, the top left hole in the cap is the #1 wire. Then the firing order as previously indicated is 1-2-4-3. This is in clockwise position. So, #2 will be the one to the top right, then #4 is in the lower right and that leaves #3 in the lower left hole. (right below #1.)
Start with this and see if it helps, and if not, then something else has to be checked, but at least your firing order will be right.

agree. my number 1 is at 10 o'clock position, then 2,4,3 in a clockwise direction.

Ok, can some one tell me what I'm doing wrong? I put the spark plug wires on the right way, and I think I timed it right. I put the (fire) mark in the center of the inspection port and I think I put the mag cap button in the right spot and the thing still don't want to start! It has a good spark. I found that out the hard way, MAN what a shock! And, Where should I put the timing mark? My shop manual says to "crank engine until NO.1 piston is on its compression stroke and flywheel timing mark is centered in inspection port located in bottom of clutch housing". Are they talking about the inspection port on the side of the clutch housing? Thanks, TractorMike

put the TDC makr in the middle of the hole (on the left side of tractor, center of bell housing). after the tractor starts and advance kicks in, you would see the "F" mark if you have a timing light. also make sure you are at TDC on the compression stroke, and not 180 degrees off. normally you pull the no 1 plug (front) and put someones thumb on the hole while you roll motor slowly. should feel it coming up on compression, not exhaust stroke. also, is it possible you took the head off the magnito, and slide the gears back together in the wrong position?

Steve, It is possible that I put the magnito in the wrong position. I'm going to try to get things right tomorrow. I will let you know how it goes. TractorMike

Since we canít actually talk to our tractors, though some of the older sect of farmers might disagree, we use our five physical senses to observe and construe what our iron age friends are trying to tell us. We have already talked about some of the colors the unit might leave as clues to its well-being. Now we are going to use our noses to diagnose particular smells. ELECTRICAL SMELLS ... [Read Article]
