2pg two stroke was running really slow and had 60 psi of compression, I did a full complete top end rebuild on the engine. New jug, piston, rings, head gasket etc, I am STILL only getting 60 psi of compression?????? It starts right up and runs but its very sluggish on hills! I have tried two different compression gauges, one is new, and the piston is in the right way. I also inspected and changed reed valve seals. I am stumped... Could I have a bad head? The vent tube also pours gas out of it, I am going to order a new carb today.
