first 15 minutes during break inn went well, then i revved it a second to 4500 rpm, knocking started.
its a very steady knocking, when i rev the engine the knocking increases also.
after 3 start ups, it suddenly disappeared.
since then i never heard a single knock, engine feels like it has power so i think (and hope) it is nothing
