hello, I'm looking for the spark advance part that mounts under the flywheel for a black 1985 gamefisher 15hp, 217.586360. The old part# on the sears website is 610880 but I think alot of the years and horsepowers might have used the same part, Eska, Ted Wiliams, etc.. Any help would be very appreciated. Trying to get this old motor to run.
