Grumpy, I believe you nailed it. The "tenants" must have at some point changed the linkage bar. I just happened to have an older style bar that only had provision for the one spring and thought I'd give it a go. The mower purrs like a kitten now instead of screaming its head off. I don't know what the difference is that it made but I'm not complaining - Thanks for your patience. Hi Mr. Davis that's a scary icon you have there - the engine number is 98902 2064 P1 01091954. This place would be lost without you guys or at least I would be. Bad photo's of the two linkages;
