When I'm not running my brand new 2.3 hp Honda outboard on my American 18 daysailer, I tilt it up. To get it tilted all the way up, I have to turn the motor sideways (tiller/handle up). When I tilt down to start, it takes multiple pulls and throttle pumps for first start. I'm wondering if the carburetor bowl drains in this storage position? Is there a better way to pump/prime prior to starting? The other clue is that when I brought the motor home from the dealer, in the same handle-up horizontal position, I had some gas leakage into my wife's SUV; not good for domestic peace!
