Don't mention it my friend.............With these old Satoh tractors, asking for information online is about the only way we can learn about them. I am working on my Bison right now, just had to float the valves and am in the process of TRYING to re-stab the distributor......I have however found a 411 source that works on Satoh tractors as well as sells new parts for them too!....** Valley Power Products / 2550 Johnson Ave. / Roanoke VA 24017 / 1-800-609-5110 / 540-345-9650....vppinc@cox.net **..........ask for Lemuel, the guys a genius with Satoh's!
