Seems there is not much information on the Tillotson carburetor fuel check valve. Homelite # 69793 in the HS151A carbs specifically. These check valves have a Tillotson part 363-559 which seems to be used across the board on all the Tillotson models.
Is this a conventional rubber flapper valve like the Walbro carbs? Appears to be a different cylindrical design. I have a LOT of trouble trusting 50 year old rubber products. We didn't need to change these valves the first several rebuilds, but the time has come to do the check valve 50 year servicing needs for most of these now. Any pics, tips. or information you might have on these mysterious Tillotson valves??
