Atco first start

Enter a word or two to search the forum section and click the Search Forum button.

Hello,

 

My 4 stroke ATCO with a suffolk motor started today. I flushed the oil twice and then ran it again but I get a loud metalic knock when under power. When I ground the plug and pull the starter there is no such noise. What do you think ? Rod Knock? 

Now I know it will run I am toying with striping down the engine and rebuilding. Any tips? 

 

Many thanks for any help,

 

James

Good point. Any ideas on how to diagnose/fix? 

I can post a video on you tube if that helps?

Basically, just take all the covers off and use eyes, ears and hands to check for loose components etc.

Good afternoon. Here is a link to a video. It had been running and is trying to run here but you can hear the clonking noise in the engine clearly......Video
