Tom,
Most likely your needle , seat & float need replacement and the carb needs complete rebuild kit along with good cleaning process.
My shop has seen quite a bit of those carbs in just the past few weeks as it's now boating season.
Along with tri-power units been building, modifying & live testing these units.
One customer left the boat for tuning, replaced old fuel, build Qjet knock off, fixed ignition issues, water tested
