If I had to purchase online (I have my suppliers as I work in the industry) I guess I would give Jacks Small Engines a try. I their service is half as good as their website, they should serve you well. Because your engine is so old, you will have to use the spec number of 105000F, to locate any parts needed. Part numbers I posted will work for both your engines. Can't believe there are no dealers in your area who will not sell you these parts, even the worst dealers around here will be glad to sell parts any day of the week, especially if you have the part numbers.
