I have a 1972 Merc 110 (9.8). When the motor is down it runs fine, but if I leave it tilted up for a few minutes then put it down again, it won't start. I have to let it sit for about 10-15 mins. then it will start. I don't see any obvious signs of leakage (gas or otherwise, and the primer bulb is hard.<br /><br />Any ideas? <br /><br />Thanks.
