Originally my motor would struggle to start and take a bunch of tries and choking etc to start up, but when it started up it would run fine. I just replaced the spark plugs, got new fuel and added some seafoam as well for good measure, and it started up quicker and ran fine to the fishing spot, but when i went to head back to the dock, it started up then slowed then power after accelerating. I am thinking i have to dig into the carbs maybe? any suggestions?
