B&S Model No. 461707-0145-E3 twin cyl 21HP Origional equipment on Craftsman Lawn Tractor 917-271840
Fuel tank beneath operator's seat was obandoned and replaced by a tank on hood well above level of carburetor. Engine ran well for several months without any problem. When 1/2 gallon of fuel is poured in tank it will now go from tank to crankcase within 2 or 3 hours. Is there a way of knowing which is at fault, needle and seat or fuel pump?
