Hey Grumpy, Found some time to remove the carb today.No water in the oil,but the fuel line was blocked.I was impressed by a wasp nest! After a light brushing & clean,I have the whole lot soaking in a mix of oil/diesel.Nothing too rusty or bad,..but bits & pieces of blockages,light rust & age to be found. My first concern is that rubber "S" shaped pipe that had the wasp nest.Possibly need to replace it,as it's quite decomposed
I'm thinking I might clean everything & replace odd parts & see if she'll start. I shall return... Thanks again, Jim
