Spark Plug Gap - 8N

[JBart]

Wondering if anyone could tell me what is the spark plug gap on a 1952 8N?
I tried going back quite a few pages to see if anyone else has posted this question and couldn't find any.

Thanks a lot.

0.025. Recommended plug is an Autolight 437.

I would recommend getting the I&T FO-4 shop manual to help you with servicing your tractor.

Thanks Colin. I just bought this tractor last weekend. The guy I bought it from told me 30-35.
I didn't think that was right, which is why I asked.

All N's say .025-.028 gap. Original spark plugs also noted as Champion H-10. Now many N owners use Champion H-12 or AutoLite 437 plugs as either are a better plug. FYI -plug threads are 14 mm x 1.25mm pitch. Before you remove old plugs, blow out the plug wells with your air compressor so dirt and crud doesn't fall into the cylinders when you remove the plugs.

Yep, .025 as Colin said. That's also the point gap on the side distributor.

Check out tip # 39; in addition to the FO4 manual, the parts catalog & operators manuals are nice to have.
