Yeah ive seen amal used on a few but I really see no difference. Amal is usually used more for higher cc anyways and they both seal well enough. Keep in mind most early victa outboards were mower to marine so they mostly used the Std carb....anyways I have a marine I may consider selling but ive already restored it so it may not suit...just needs a correct filter assy. Its in the forums somewhere..engines I think?
