I have noticed a knocking noise in my KQ when I start it for a few seconds and it goes away. In the past few days I have noticed the nosies when at idel. I recently changed oil and filter so I have checked several times for a leak. Any suggestions or am I just paranoied from the reverse issue.

 

I think i stated this on the other forum... Get your valves adjusted....thats the problem. I had the same thing happen and its the valves for sure.
