Rob it is faulty, it starts, runs perfectly for 3 mins then cuts out.
then it will start again but as soon as I let go of the key it stops. i think its the low oil cut off that is faulty I'll need to look into it next week. I think the seller knew something was amiss as he constantly told me it needed an oil & filter change so will give it a full service next week
although the 3 mins it is working it runs beautifully and show the pump is working with no problems.
every thing else in the sale is fine
