to activate the the choke on my 3.2 i attach a 2-56 threaded nylon clevis to the choke. drill a small hole in the cowl that puts a threaded pushrod inline. you can align the clevis and pushrod through the front of the cowl.simply screw it into the clevis and snip it off the desired length.pull to choke push to open,when you want to remove the cowl,.........unscrew it..........simple and works great on my others
