I have a 1985 force 85hp model# 856X5L.I have carb bowl gaskets leaking. When I pump my primer ball there is no leaking only at 3/4 to WOT.I removed the carbs to have A look at the needle valves and clean . installed #3 carb IN #1 spot just to hook up fuel line and test by pumping primer bulb and no leak pumped up fine.When I removed the carb to mount in the proper position I turned it sideways A little and have leaking from bowl gasket.Is this normal?
