I recently acquired a non running Mercury 100hp 2t. Within a few hours I got it to crank up and run. 125psi on top 3 cylinders 119 on bottom number 4. Timing is all dead on, can hit the key and it'll fire right up and idle. I deleted the oil tank and pump so I could 50:1 premix.
My problem is. I cannot get any throttle response out of this engine. Within the first 10 minutes of idle it's loading up. Won't shut off but man o man the smoke. Raise the rpm to clear it up some engine levels off and cleans up. Drop it in gear throttle up some and it's like it just goes into limp mode. It's a junk yard motor. Multiple engines to make 1. No serial numbers that I know of, from what I can tell it's a complete engine with safety stuff and alarms. Just zero ass when it comes to running. Almost like it's lost its 2 stroke "power band" and sound. Sounds nothing like a high strung 2 stroke when revving. Almost instant rpm drop after throttle decrease. It doesn't have that ping ping ping like a chainsaw.
