Ok update time. I pulled all of the plugs and turned it over sounded good no clunking or clanging that I could hear. Put the plugs in with new wires. Started it up and clunk clunk. Let it run for about 5 seconds and shut it down. Didnt notice any smoke coming out of the pipe. I got my wife outside for a fresh pair of ears and she heard the same thing. Not sure what the next step is. Any suggestions?
Thanks
