Remember I have NO GAS in my motor so my pictures show my float needle tip down.
Yours will be up and near the primer lever end.
Now your Sea King is running but it is kinda doggy, huffing and puffing. Slowly move your mixture
knob CW until it starts running well. You will need to fine tune this needle position to find your Sea King’s
best running setting. It may take a minute or two and a few tries to get it perfect. This is where you need to
keep your adjusting needle/HS needle still while moving your knob and primer cam positions to where you
want them permanently. Note knob center-line is vertical and primer cam tip is away from the primer lever.
Here is how I set mine:
So the pic showing the closeup of the hs knob…that is with the hs needle set at the approx 1/2 way open setting, then adjust for best tune once warm and reset knob and cam to same relationship?
The picture above is my warm engine running perfectly mixture knob setting. The red circle highlights
the position of the primer cam tip. It is “up and out of the way” of the primer lever. You can not have it
so close to or dragging on the primer lever. It will cause a flooding condition. This is why you need to
study the diagrams. You have to understand the relationships of these moving parts. Your settings do
not have to be exactly like mine. The picture also is my warm start setting.
The “1/2 to 3/4” or “3/4 to 1” number is an arbitrary number. It is used to get you in the ball park
for starting out only. When you disassemble something for cleaning or repair you need a “starting point”
don’t you? Well “that number” is it!!! Once you get your Sea King running perfectly “that number” may
be 5/8, 1 or 2/3. It does not matter what it is. It is your number. It will not be exactly right for one of my
Sea Kings. Now when you find “your number” you will need to adjust the primer cam and mixture control
knob’s orientation so that it works properly together. You can set them any way you want visually as long
as the assembly works correctly.
I’m showing you how I do things for simplicity and ease of operation. Best of luck.
Sea Kings Baby!!!
