Evinrude Speeditwin 22.5 starting instructions

[bsplit]

I picked up a Speeditwin at Mark Suter’s meet last fall, and just got it running after cleaning the carb, and replacing the condenser. However, the instruction decal on top of the tank is toast. Does anyone have a picture of the decal?

Thanks,
Jim

Many find the shear size of this antique intimidating. Just pulling on the rope to turn it over can take considerable effort, However both cylinders going on compression at the same time also means you have almost 40 degrees at the bottom of the cycle when the ports are open and the outboard turns freely. So, the starting technique is to wrap the rope around the rope sheave so that turning it counter clockwise gives you about four inches of free rope. This gives you the ability to bounce the flywheel back and forth at the bottom of the stroke. Timing the force of your pull to the clockwise bounce of the flywheel will give you the added energy to easily crank the motor. . . 😉

As always……thanks a lot for your help, Garry

Based on advise from Jay Walls, and through personal experience, I’ve found these things start best if you prime the living daylights out of them when cold. 8-10 shots with the primer is not too much.

Hope this helps.

Have you run your Speeditwin yet? Don’t be intimidated by it. When everything is set right they start easy and run like a top. Very well built. I have a 1949 6039 that I run every summer. It’s one of my favorite motors.

My Elto Speeditwin was build from parts in 1950. I haven’t put the Elto decal on it yet. . . 😀

How many quarts of oil per gallon of gas is recommended?

[garry-in-michigan]

In 1947 a pint and a half per gallon was recommended. I have been experimenting with a half a pint of Synthetic TCW3 and half a pint of Low ash aviation 40 weight oil. Lately Steve Woods has been mixing the fuel and I am not sure what it is , but Steve uses it in his Big Four. Dad used a gallon of SAE 60 weight to four gallons of unleaded high test gasoline in his Big Four, but it was extensively re-engineered and ran his 13 foot Lyman to a 54 MPH two way average through a measured mile. . . 😉
