motor doesn't want to run 'slow'- it will start, gradually begin to race- when the throttle is adjusted, it wants to either die or race -but not run slow- when it dies, it acts like it's flooded(?) and needs to start w/choke on- In addition, when I put it in gear (F or R)it kicks up on the tilt (out of the water)and I have to reset it- TIA
