I put in a small battery to see if it would start, It turned over (Slowly )but would not start.(Battery Ran down) I went and got the battey that is suppose to go in it. Now it will not turn over? I have check battery conection there is no corosiopn at all and a very tight. Could the bushes in starter be stuck? Thank you.
