Hi.. I have been trying to get my 1954 Elgin outboard to run good so I can take it out to the lake with confidence. It's in good shape and had been worked on several years ago by a vintage outboard repair place. It starts up on the first pull but it stutters and stalls out after a few minutes. I'm not having success adjusting the carb Run control knob and the smaller brass like knob marked Rich at various speeds from start to fast. I have the Rich knob turned about 3/4 turn to the left after it was fully closed all to the right.
I'm attaching a picture of the front of the motor ( elgin front.pdf ). I'm hoping if I explain what I'm doing you guys can critique and tell me the proper steps. To start I use a 16:1 mix using Quick Silver Marine Premium 2-Stroke with pump gas. I reached back out to the guy I bought it from and he said he used that and it ran fine. So I figured keep it the same.
I open the small gas tank knob on the top of the cover all the way to allow for air to help the gas flow. I open the knob on the lower right all the way to allow the gas to flow into the engine. I put down the choke and place the Magneto switch to Start. I put the carb setting on Start. The red ball knob on the left side is in the far back position. I pull the cord and the engine starts.
Now I let it run for a few seconds then flip up the choke. As it runs then stutters then abruptly stops
I let it run in this position and move the carb Run knob control and/or move the Rich knob to see if I can get it to run better. At lower speeds like in Start or Shift on the Magneto switch (when I Shift on the Magneto I move the red ball lever to the forward position. I tend to stall out more. At slightly higher speeds of moving past Start on the Magneto switch past 2 or 3 dots towards the Fast I tend to stall out less but still stall out. On the higher speeds I move the carb Run knob toward the center around the word Run. I might move the smaller Rich knob a little as well. Most times after a few minutes the engine stall out.
When should I be adjusting the Rich carb knob? Do I have it set correctly at the 3/4 turn to the left? Do I need to keep the carb Run knob in the Start position each time I start the engine? How much of a turn and at what speeds should I be adjusting either the Rich knob and the carb Run knob?
I would love to be able to take her out on the water. Is there a certain procedure to follow at low speeds (what knobs to turn and how much to turn) and at higher speeds (what knobs to turn and how much to turn). Do I have all the knobs turned correctly on my start up. Do I ever adjust the knob on the lower right, the one for the gas to come into the engine? When would I move the carb knob on the Lean mark? Sorry for all the questions. Any input would be appreciated. Thanks

The top has about a gallon and half of gas/oil or so in it.
