Got to tack it out morning
Would this help
Primary cause of hard cold start: operator error.
Open gas tank vent, pump primer bulb until it is firm, raise hi-idle lever full up, push the key in and hold it in while turning it to "start".
If you can flood your engine with the primer bulb, then your carbs need rebuilding. Pump the bulb until it is firm - that fills the carb bowls - they have a float valve that closes when full. This is true of every carbureted 2-stroke outboard ever made.
"Pumping the throttle" is useless - these are not automotive carburetors - all it does is open and close the butterfly valves.
Your motor does not have conventional choke plates; instead it has a primer solenoid, which opens a valve and allows fuel to drain into the cylinders to richen up the mixture for cold starts. You should hear the solenoid "click" when you push the key in.
Bad compression leads to hard cold starts - you should have at least 100 PSI in all cylinders, and the lowest needs to be within 5% of the highest.
If you have good compression and spark on all cylinders, the primer solenoid actuates, and the fuel line holds pressure, then you need to remove your carburetors, dissasemble, soak overnight in carb cleaner, blow out passages with compressed air (or aerosol carb cleaner), reassemble with new kits (including new o-rings, gaskets, and float valves & seats), reinstall, link & sync, and adjust slow-speed mixture

Carbs probably need to be cleaned and re-built. Common problem in outboards that havent been run in a while

There is a switch in the control box that locks out the start unless you are in neutral. Open the box and put in a new switch,this is a safty device to keep it from starting in forward and throwing you out of the boat. Jim OMC retired Mech

Clean or replace and set points to .020. Also replace your condenser.

Need year mode?. But you can go to this website and get all you need. Don't worry I'm not a salesman. I just use this site for my own business. www.crowleymarine.com. click on parts catalog then follow directions.
