Hi Parkboy. Did you ever get the self propel to work good enough on your mower ? I see this thread was started about a year ago. I have the same mower and couldn't get it to pull by itself good enough to use. I found this one in a garage that was packed to the ceiling and wall to wall. I just saw the green handle bars sticking out. When I saw the green, I thought ahaa, rusty gold, like they say on American Pickers. Well anyway, I put new drive rollers and new correct tires on it and still couldn't get it adjusted good enough to work properly. So I swapped out the top handle bar and cables and now it is a straight push mower. It is a
1989 strong running F series mower. I was just curious to see how you came out with yours.
Jerry.
