Hi, new here. I have a 2005 Tohatsu 18hp 4 stroke. When I had it winterized last year the dealer rebuilt the carb, replaced a starter solinoild, and fuel line. The first time I took it out it was hard to start, and sputtered when giving it throttle. This weekend took it out was hard to start and as soon as you put in gear it would sputter and shut off, never did to get it to run. Any ideas? Thanks
