This is awesome.

Got the pipe from TSC. Did not like the flapper rain cap, found this 45 degree tip online. It was an ID/OD clamp style, which I did not like, so I welded it on. The tip was hard to find. Pipe is odd size, like 1-1/4 OD. Galvanizing burnt off, but the black powdercoat has held up good. When plowing I have to remove and put the horizontal back on. The vertical pipe vaporized the gas in the carb bowl and caused it to miss like it is out of fuel. Philip.
It is too bad that vertical exhaust causes the miss. Thanks for pointing that out as it is something I have often wanted to try but never got around to. One of the very few things I do not like about my 8n, especially when plowing in warmer weather or doing other extended-hour, high-hp work, is the hot foot on the right side caused by the horizontal exhaust located under the running board. I also had trouble tearing the exhaust out from time to time on rocks and deep furrows when plowing. These days, like SG, I prefer deisel power for most of the heavier jobs like plowing and brush-hogging and my own 8N is relegated to mostly lighter work like planting or hauling firewood. I have also had good luck with points on the 8N, putting a new set in more than 20 years ago and not needing to touch them since. One thing that I believe helps point life on these old tractors is leaving them 6 volts. It seems that converting to 12 volts consumes a good bit more points. I converted my Farmall cub to 12 volts, mainly to operate a diaphram pump for liquid nitrogen & roundup application while cultivating. Since doing that, I only get 4-5 years out of a set of points.
Hardness of valves and seats can be an interesting and continuously evolving with changes in metallurgy and fabrication methods.
The hardness of a 1950 valve and seat compared to a todays valve and seat really involves knowing the metallurgy and fabrication methods used.:thumbsup:
The word "Hardened" per say really doesn't mean much.
