Hi Deejay
Check the fuel yeah plenty of fuel at any tap setting,does the needle ever wear out ,looks in good condition,have cleaned the seat with a cotton bud clear and clean i think it must be flooding cause when i try to start mower with a couple of prims on primer it appers to have flood itself ,then it takes a 100 pulls to clear fuel in crankcase it will then start but have to have turned on fuel about a 1/3 as if i have set the amount of fuel entering like a viarable jet know what i mean thanks gray
