8n issues

Srock67 · Jun 27, 2018

Hi guys,
A couple weeks ago I bought my first tractor a 52 8n. It started and ran great when I bought it and the several times I took it out for a drive. However the last trip I took I was going down the road in fourth gear when it stumbled and acted like it was running out of gas. I messed with the shut off valve and was able to keep it running but just barely and gimped it home. After reading stuff on this site and others I figured it was a fuel problem. I have flushed the tank, new gas, cleaned the fuel line, cleaned screens,Replaced the shut off assembly, and taken the carburetor apart and cleaned it. I have fuel out the bottom of the carburetor drain plug when shutoff is opened.
My problem is this, it will start every time but barely idol roughly and I have zero throttle response and it will run for around a minute and then die. And it will start right back up and do the same thing over and over.
Just hoping maybe someone else has had a similar issue or could point me in the next direction any help is appreciated.
Thanks, Kenny

Replacing the capacitor cured my neighbor's 8N with the same symptoms.

Welcome to the forum. Check spark quality with an adjustable
gap spark tester. ~$8 at most any auto parts store.
Spark should jump a 1/4 inch gap in open air on the tester.
You could also use an old spark plug opened up, but you'd need
to hold that against a good, bare ground to get a reliable test.

The points on these tractors need to be cleaned, gapped and lubed
as part of a regular maintenance schedule. When replacing them,
replace them with good quality points. Not the cheap ones with
a plastic rubbing block like sold for cheap online and not so cheap at TSC.
Standard Ignition BlueStreak FD-8081X or Echlin CS753 for example.
