Ive a JS40...caster steer... The issue is the engine, and this issue may be with other engines as well. The motor on this a Briggs 7.0HP OHV (190CC). After it sits for a day or better, I go to pull the start rope and it seems the cylinder has locked up. Let me tell ya, this engine takes no sh%t. The chassis, the self propel system will run at a lite "jog" if you are capable jogging behind it. No joke. And it will cut too, beautifully and flat, at that speed. I dont know if fuel is continually leaking into the cylinder while it sits causing a hydraulic lock, or if it's another issue. I have broken two starter ropes and almost cut my fingers with "snap back" from this.
No announcement yet.
