How do I determine the correct timing of the engine. The engine mis-fires and will not run at high RPM's. The tractor ran find last summer/fall. Now, just like that it mis-fires bad and has difficulty staying at an idle. Cap, wires and plugs have been replaced.

I located the problem. I recently purchased the Tune-up video and came across one of the answers. When I replaced the Distributor cap, wires, plugs and rotor,I put all of the wires back exactly the way they were. I did this because I did not have the manual with the firing order and piston designation. When I watched the valve adjustment section, it dawned on me the whoever tried to repair the tractor before me, had the number four piston as number one. This was a vital error. Once I corrected the firing order after finding TDC of piston one. It ran much better. Once I replaced the points, everything worked great.

Thanks to everyone that assited me with this issue.

I would doubt if the timing is the culpert here, it sounds as if the tractor was inactive over winter. The timing wouldn't change unless someone is messing with your tractor. What can happen to these old Allises(and others)is that a valve may stick in the guide. I'd first pull invidual plug wires and see if you have a dead cylinder, and if the Ignition system is ok I'd do a compression check if a cylinder is dead. If a stuck valve is the problem you need to check for a bent push rod too. Could be fuel or ignition, but I'd check indvidual cylinders first. Happy trouble shooting.

I did something stupid and you may want to check yours too,, I wired my WD45 without thinking, I wired it like one of my Farmall tractors 1=3=4=2 instead of 1-2-4-3 it runs but not right,, check your firing order,bfore finding what I did I had cleaned the points,regapped them,changed plugs,cleaned the carb and set the valves(all good things to do but wasnt the problem),,Jim

Reconsidering your comment, I doubt that timing is your problem unless your points and condensor are bad. Sounds like it could be a fuel problem. The lack of high speed could indicate an obstruction somewhere between the tank and the carb or even in the carb. Missing can be caused be uneven fuel flow. I'd start cleaning up your fuel system after I'd checked the points.

Most folks just loosen the screws and rotate the distributor until the engine runs the best. I've never used a light on any of mine.
