I have a 2001 Mercury 175 EFI. It recently got new plugs, filter, and throttle cable adjustment. The motor runs wonderfully. The first start of the day is on the first crank. Now that the weather has turned cooler, I can run it for a while with a decent warm up, then stop at a spot to fish a while (hour or so). When I go to restart the motor, title crank and crank, but has difficulty turning over. I can trim all the way up and give it gas though the foot throttle and it starts better. I'll burn off the excess gas and it riluns fine after another warm-up. It smells like the engine is flooding on the initial crank that doesn't turn over.
Compression is good, bulb is tight when I think to check it, no engine faults (at last check).
