Tenderly,, on your two stroke,, use full choke to get started-- click to half- while manipulating throttle to idle as smoothly as possible, depending on temperature this doesn't take long.. turn choke off as soon as you can as u you throttle it also,,= to run smoothly till half rump warmed up,, about 4 min.. then pull from dock ,,putt down river,, = another 4 min. then open it up on frozen lake as soon as possible....
