My 1989 L21ZSNA "self propelled" did not propel very well. So I found a pair of new old stock rollers and replaced the originals that were worn down. I have adjusted the clutch rod so the wheels are 3/16" away from the drive rollers when the machine is in neutral. Now it pulls good down hill and on flat ground but that's about it! Is there something else I can do, or is this as good as it gets? A boy my age needs all the power assist he can get!!
Thanks,
