I guess the first thing I need to know is where is the ID tag on this engine? I have it out of the mower and have rolled it over looking with no luck. It is out of a 1985 Deines 1860 zero turn. Thinking I will need engine serial # and Model # before I tear it down. I dont see anywhere that looks like a tag has fallen or been torn off. There is some grease/dirt sticking to it though. Then I am wondering if by unplugging the 3 wire plug coming out of it (for the charging system & engine kill) will allow it to have spark? Also is there a history of the starters on these need repair often? big battery in my truck won't spin it hard enough to engage the starter gear.
