I have recently dug out my old 4hp 2 stroke evinrude, stripped down carb, cleaned fuel lines etc and replaced impeller in water pump. It starts and runs but I need to keep the choke on. Any suggestions would be great.

It will run for fine for a while with the vent turned off. I would clean out the passages in the carb. ( fish leader wire, carb cleaner, air. Use goggles.

sounds like it needs a carb kit/ overhaul.....but some seafoam in your gas, since it runs, can do wonders for 10 bucks.

Found a wee bit of dirt in main jet in carb. Fish wire did the trick. Running like a dream.
Cheers
