Clean your carburetor's main circuit. Your carburetor contains two "circuits." One is the main circuit, and it puts gas into the engine with the "choke" off. The other is the enrichment circuit, which puts more gas into the engine because a cold engine needs a richer fuel/air mixture than a warm one. If your engine only runs with the choke on, that means no gas is coming in via the main circuit, which means it's clogged. Clean that out good and it should fix the problem.

When you say the engine will turn over only when in choke, I assume you mean it runs while chokedand then dies when you let off the choke. Check the fuel filter,the air filter,makecarburetor adjustments if necessary and ultimately, checkthe throttle linkage.

How do you adjust carburetors on 1965 evinrude out board motor Runs with the choke on?
If it runs with the choke on, Then it will not do any good to adjust them. It is running lean/ not getting fuel. The carburetors have dirt in the fuel jets and that is why it won't run when choke is off. When choke is on that richins the fuel up and it try's to run. Need to clean the carbs out.
