Yellow stone,
If I may say also don’t jerk on the rewind to start, it will hurt the engaging pins. Pull out until it engages, then let her rip. I have a 54 Evinrude but not used much anymore. I always ran it on 24/1 oil ratio until I read the inside of the hood. Evinrude stated instructions stated for ease of mixing add one quart to a five gallon of gas container, add 1 gallon of gas, then shake & mix. Add the other 3 3/4 gallons of gas to make 5 gallons of fuel. I don’t know the ratio, little less than 24/1 mix but I NEVER had any issues & ALWAYS had the same easy mix.
