[QUOTE="SAABologist, post: 490759, member: 31667"] Thanks for your advice, I am a little stumped. What could cause running bad at first, then running great? Here is the situation: Starts instantly and idles great at all times. During first accelerations, it bogs down on acceleration, then runs rough like it's not getting constant fuel. After a few minutes, all is well and it runs great, including backing off and accelerating again. The Motor: - 40 hp 2 stroke Mariner 1987 Fuel connector to motor is brand new and the hose from tank to motor is 3/8" fuel line in great shape. All hose clamps tight. Scepter 6 gallon tank with the pickup tube repaired a couple weeks ago. I did open the vent on the cap. Thanks in advance for your suggestions! [/QUOTE]
