[QUOTE="KAI, post: 55754, member: 580"] ok hello guys and gals, I think i got a 1990 2 stroke 15HP mariner outboard motor, havent started it for like 4 months. i just started it, it runs good but seems to backfire when in high idle or when i throttle up. just wondering what cuases it to backfire? i am new and have no knowledge on outboard motors my guess is: "could it be the spark plugs?" any help would be apprieciated! on another note: how often should you start your outboard if you dont use it for a long time? once a month? i can post pictures or video if need to! THANKS TO ALL THAT CAN HELP......... KAI [/QUOTE]
