[QUOTE="Farm Boy, post: 3412208, member: 75801"] It sounds to me like the pump is delivering to much flow under load for the size of engine, and that your system hydraulic relief valve (if equipped) might be set to high. If your 2 stage pump is not unloading the high volume section when the cylinder meets load (the log) and the relief valve is set too high, you are going to stall the engine. When the cylinder starts into the wood, does the cylinder change speeds or does it try to continue to advance at the same rate. A high/low (2 stage) pump should dump its high volume section somewhere around 500 to 800 psi. If you see an acorn nut on your pump, that is the sequence adjustment for unloading pressure for stage 1 (high volume section of the pump) Depending on the manufacturer, they are adjustable between 200 and 800 psi. It is possible a contaminent is caught in there causing it not to function like it should. [/QUOTE]
