sometimes when starting my 272 it has a sharp knock that is loud for about 30 seconds to 1 minute. it will do it first start in the morning but can do it when its hot its coming from the left side but being partly deaf its hard for me to pick up what it is i know its not a tappett noise & by the time i get under the hood its gone. normally its as quiet as a mouse any ideas. thanks.
