I got the hydraulic problem fixed with your great suggestions. Thanks again. It was partly valve related and partly cylinder related.
I am now in the market for some new decals and some knobs. A red and a white knob for the throttle and choke would be good but I am not really that picky. Any ideas? You would think the knobs would be plentiful, I see a number of lawn tractor/mower companies use them, including walker. So far I have had no luck finding them.
