1996 40hp evinrude. new power pack new coil, new wires and plugs.when i pull the plug wire off on the top cyl it drop a little in speed when i pull the bottom cyl it stall out. comp. 130 on bottom cyl and 127 on top cyl. I can not get the timing to go pass 15 degrees it should be 19 degrees the spark on the top cyl is not as strong as the bottom cyl.
