1. Sounds like you need to clean the slide, it's sticking. When it suddenly pulls up that puppy wants to go. YEEEHAAAA!
Try an ounce of seafoam in the tank. Should be better before you run out of gas. Or take the top off and use carb cleaner. Don't get it on the rubber. Soap and water if you do. Becareful, it's a $90 part. When you clean the slide don't leave any fingerprints on it when you put it back.
2. Then you shut her down hard, she barks at you! Could be 2 reasons, maybe you got your idle real low. When you shut down hard it over shoots and kerpow. second reason you might have the idle open more than neccessary, so you have to turn the idle speed lower than neccessary. I generally have my idle high 12 to 1300. benefit is more oil to the head while idling. a good thing while warming up.
