So yesterday evening I replaced the exhaust manifold and muffler on the old ferguson. Today I fire it up to plow snow and and all of a sudden it's only running on 3 cylinders! Did I screw something up when replacing the manifold? Ideas as to what could have caused this? Recently replaced the distributor cap, rotor button, points, condenser, plug wires and plugs. Coil was also replaced some time ago. Tractor has been converted to 12 volt.

Did you use original bolts?
Other than that, I would change plugs, then check compression.

I used original bolts on everything except the muffler clamps. Plan on picking up new plugs tomorrow.

I don't actually. I think that is something I need to get.

Yeah, for less than $10, you're able to answer many nagging questions.

Except the meaning of life... That one is either Garden Tractors or Family... Not sure yet.

If all you did was replace the intake gasket look for an intake air leak at the cylinder that is not firing.

I assume all was well before.

Didn't think about the intake being in there too.
I still think plugs, but it'd be worth it to spray a little carb cleaner or starting fluid along the intake gasket to ck for air.
Just watch, this new stuff will peel paint.

I think WD40 will alter firing too without the chance of paint peel.

Changed plugs and that didn't work. Sprayed carb cleaner around the gasket and that didn't alter the firing......I am suspicious that the new manifold may have a casting defect in it not allowing fuel to a cylinder. I got an inline spark tester and I have spark to all 4 cylinders. Next I am going to check compression just to make sure it's not a valve or head gasket problem. Any idea how many psi of compression I should be getting out of that engine?
