Noticed it when idling then turned motor off , waited minute or two then started.
at idle had a (stumple) or clunk sound while engine was idling turn it off ASAP
First i have no manual or operation guide to work with for a guide.
Power-head has been rebuild 1 half year ago, and out of warranty.
I am going to take the cawing off tomorrow and remove the plugs and get a compression tester.
check the cylinders and hope for the best , I was really hesitant to run the motor and trolled back to the ramp about 2 mile .
Really wanting to know what this alarm means concerning crankcase logo.
and could the oil injection system be tied to this ?
Oil tank was half full.
Thanks John
