I've just purchased a 1967 Harley Davidson 3 wheel golf cart and was told that it ran. I wasn't able to start it at point of purchase because there wasn't a battery in it at that time and the guy that I had bought it from on Ebay wasn't there, just one of his employees. Anyways when I get it home, I put a battery in it, turn the key nothing. So I got to thinking, maybe this is like the old cars, turn key, depress gas pedal. In what I thought was neutral position on directional switch I was getting nothing, until I would swith to reverse or forward....It would crank and I would spark on the points, but engine isn't starting. What am I doing wrong?
