Success! I dremeled the top screw off and the bottom one immediately loosened. I am going to replace with allens moving forward. A couples questions:
1. Do I need to loosen the throttle cables to get the tabs out of the original plastic throttle housing or can I just pull and pop them out? I am putting a metal Moose open ended throttle on. Any tricks appreciated!
2. What grease is used on those cables in the housing. Is it something special or can any grease be used?
I am going to go with the foam tape trick to locate my drill points for the tabs.
