Okay, I've been having this old motor for around 4 years, and honestly had nothing but hell with it since buying it. (Picked up for real cheap only reason I did) I've learned the hard way about what to, and what not to do when working on and replacing, changing parts, and making adjustments on this motor. My most recent and first issue I have not been able to troubleshoot is the motor not turning up rpms. I swear it's like my 9.5 hp downgraded to a 3hp. And cannot for the likes of me figure out why. I just recently replaced the entire powerhead, bc I stupidly broke a headbolt off in the block and failed to tap it out. I had decided to check be sure a leaking head gasket wasn't my issue. So replaced entire powerhead. Cleaned carburetor thoroughly and rebuilt using kit.. after soaking in chem-dip for 24 hours. Inspected armature plate, went over coils, points, condensers, shorting wires, everything checked out. Reassembled the entire motor, mounted in a drum. Hooked up fuel lines, cranked her up. Fires on first to second pull at most. Idles decently. Put in gear, and attempt to speed the throttle, hardly no response. Motor hiccups often, and will not turn up hardly 1/4 of what it had before problem began. Why does my motor have no power????
