SOURCE: what is the correct fuel/oil mix for evinrude 4hp ?

Your tech may have missed one or two parts of the idle circuit. There is an idle mixture screw hidden under a brass plug (to prevent tampering on the top of the carburator. This passage needs to be cleaned and idle air mixture screw adjusted properly.
There is also an idle air jet located close to the idle mixture screw. The jet should be removed and cleaned as well as the passage that it came out of. The jet is a small brass piece with a small hole and a standard screwdriver slot. Unscrew this, spray brake cleaner through the little holes and spray brake cleaner (using the little straw that comes with the brake clean) into the hole in the carburator. Take some compressed air ( from a small can of compressed air that you use to clean your computer) and spray into the hole. Reinstall the jet and see what happens. If this does not fully fix it, I would return it to whomever originally cleaned it. If the dealer is worth their salt, they will fix it (if they did not clean in the first place) Everybody makes mistakes.
Also, be sure that your oil level is not too high. It is better to be a little low than too high.
Be sure to be using NKG spark plugs DR5HS I assume that both spark plugs look ok.
The other item that affects this motors idle is the thermostat. Feel the top head of the motor. It should be about 130 degrees. Not hot enough to only just touch, but not cool enough to be able to keep you hand on for 10 seconds or more. A temperature gun would tell you for sure, but most people do not have those is their back pocket.
Timing could be an issue, but normally, it would affect all speeds of operation.
A lot of things for such a little motor.

You have probably already found an answer, but all the specs are in the owners manual. If you do not have one, you can download one for free from honda-marine.com under the owners section. You will only need the serial number for your engine.
SOURCE: 40 hp mariner outboard 2 stroke oil leak at
without seeing it in front of me its difficult to advise,i had a mercury but it wasnt oil injection so i iam not sure exactly how this injection system works but i should imagine its nothing more than a O ring thats perished or a copper washer needs cleaning with some wet and dry.I bought a new 4stroke mercury in the end because i got fed up with fuel consumption from the 80hp two stroke ,this four stroke 50hp will do about 12 14 nautical miles to roughly 6/7 litres of petrol at about 1200 rpm because iam only a sunday driver and the bumping on the waves makes my back ache unbearable,Well this is the land of fiesta /siesta /manaña --spain .Have a closer look and see where its leaking its only a mechanical pump running off the engine ,so it will have a push rod with some sort of diaphragm that pumps a tinysquirt of oil into the crankcase so it can mix with the incoming fuel ,nothing complicated
SOURCE: 90hp 4 stroke suzuki outboard how do i reset the oil alarm?
TO RESET:
1. TURN IGNITION KEY ON
2. PULL OUT THE EMERGENCY STOP BUTTON 3 TIMES IN TEN SECONDS, A SHORT BEEP WILL BE HEARD IF CANCELATION WAS SUCCESSFUL. TURN KEY OFF AND PUT EMERGENCY STOP LANYARD BACK ON ITS BUTTON
