1956 Evinrude Lark 30 H.P Throttle Linkage Problem

[Psiclown]

Hello,

My drunk friends were messing with my motor and broke the control lever pin. I went to put on a new one tonight and can't figure this out. I never saw how it went on in the first place and can't find a good diagram in the manual. The lever in the picture connects further inside the motor with a spring and that's where the issue seems to be. Can anyone help me out with this?

Thanks.

Here's a better picture of the problem spring.

It goes like this ....

This is one of my '58 Bigtwins, with an added fuel pump.

Nice thanks for the pic! Do you known how the other lever attaches internally?

What "other lever" are you refering to? It looks like everything is hooked up in the pic. The levers and arms are used to advance the timing (magneto) CCW as you twist the throttle. The armature should go CCW while the flywheel goes CW. Can you see the magneto rotatting as you twist the throttle? Does the buterfly valve open when the cam on the magneto engages the roller a la lync and sync? If so you're probably good to go.

The lever that you "arrowed," attaches to the bottom of the armature plate. It is what moves the plate and advances the timing, as you twist the throttle.

The capped pin that is on the throttle control rod, goes through the throttle lever (shown in my photo, missing in yours) and the timing advance lever. I don't have a parts diagram in front of me, but if my memory is correct, there is a hole in the bottom of the capped pin for a cotter pin.

The issue is when everything is hooked up correctly, the throttle only pushes to "start"...not fast. The timing advance lever is the problemo.

Psiclown, you'll need to shift her into FWD to get full rotation. The motor doesn't have to be running, jsut in gear. You may need to spin the prop a bit by hand to help it slip into gear. There is a vertical, spring loaded, shift lever on the right side of motor (when viewed from rear), which prevents the armature plate from rotating fully when in neutral. When you shift the motor into gear (FWD or REV for that matter) the shift lever will move out and away from the body of the engine and allow the armature plate to rotate fully. Not sure if that's what you mean, but give it a try. Everything looks to be hooked up correctly otherwise. Keep us posted.

Well that explains it perfectly thank you very much!

No prob. I've been stumped by that one before myself. It's kind of a clever idea b/c it keeps you from over reving in neutral with no load.
