Farmall h hard to start

Postby Brockpend » Wed Sep 08, 2021 5:47 pm

Never had any trouble starting my H before m, no choke or anything was ever needed. All of a sudden like 2 weeks ago it started becoming really hard to start. I’ll eventually get it to run but It’s hard. Once it’s warmed up it will start back up no problem. What could be wrong?

When's the last time it had a tune-up? Mine did that, and new spark plugs made a world of difference.

I can second this. Different engines, but I changed the plugs to NGK's on my C and had no trouble. Just don't use new Champion plugs. My auto parts store quit carrying them due to quality problems. I also changed the distributor wires, coil, tweaked the timing which made a huge difference, and eventually set the value lash.
