I recently bought a 2006 Lowe with a 50 hp mercury on it and lately it seems to start hard and won't idle until it gets warm, also smokes a lot at cold start. I pulled the plugs and they look good, and it runs like a champ once it's warm, no problem at high speed, just cold start. I always pump the bulb till hard and have to choke it till it smoothes out. Any help would be appreciated. Thanks
