Can any one confirm that I should use p/n 174977 (Premium Blend)as opposed to Hi-Vis or Ultra-HPF synthetic? This model is not an electric shift, but the recommended usage on all these labels seem somewhat ambiguous. Thx. <br /> :confused:
Anyone know the correct spark plug gap? It's mis-firing at idle and I'm looking for the culprit...so any other thoughts would be appreciated as well. Thanks. :confused:
