720 spark plugs

Recommended Posts

cncman08
I am running autolite 216 spark plugs in my 720. I am wondering if these are the correct plugs to run. They look a little light in color, but it seems to run well. What plugs are you guys running out there.

It could be a heat range problem or or a slight overfueling (rich mixture) condition. I assume you do not have an oil consumption problem and how long have the plugs been in the engine? Also I am assuming that the correct crossover brand plug is being used.

What is the product number of tractor? You can download an operators manual here and that will give that information.

Here is a good cross over guide. http://www.ihcubcadet.com/IHCCFAQ/SparkPlugCrossReferenceChart.htm Some of these plugs are a hoter plug. Onan part # 167-0241 non resistor plug # 167-0237 resistor type plug Motocraft = AL-5 Autolite = A5 or 3926 I am using a Champion H-8 and runs fine.

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁
