Exmark Lazer won't start. I bought it used a couple of months ago and it has run great. Went out to start it a few days ago and it won't start. Turn the key and get a click in the back of the engine. The levers are out, the brake is on, I'm sitting in the seat. Replaced the battery but that's not the problem as well. Can pull the PTO out and turn the key and hear another click so I know it's getting juice and contact in the back. Would like to hear from you guys before I wind up spending lots of money on the dealer. Thanks a bunch for your help.
