I haven't had time to get it running yet. It has 2 year old fuel in the tank that I have to drain. I need to drain the oil and check the filter for metal shavings. It was suggested that I put thicker oil in it and try starting it. I was thinking about using diesel engine oil (15W40) or something like that. I hadn't thought about the fuel pump/pushrod going out. Could that make a hammering/knocking sound? I'll have Monday off, so hopefully I'll get it running then.
