I want to activate the choke on a 3W75 with a servo. The choke actuating arm locks into position when open. How do I alter the choke arm mechanically to overcome the detent? It looks like I need to install an extension arm on the choke at 90 degrees so the arm will swing thru a 30-45 degree arc from closed to open. Does anyone have a tried and true setup for this situation? Will a standard servo have enough torque to pull the choke out of the open position to closed?
