Yanmar throttle

[rchad]

The throttle cable on my Yanmar 2GM20F is very difficult to move. I disconnected it from the engine and found that the problem is not with the cable linkage but with the arm that connects to the engine itself. Why is the arm so difficult to move? Any help would be appreciated.

Those arms sometimes only move easily when the engine is running...

The speed control arm is difficult to move whether or not the engine is running.
Seems to work just fine, just seems that it should operate much more easily. I have to put a lot of muscle into increasing and reducing throttle.

Is there a drag device on the throttle cable ? Is it always like this ?

rchad,

Curious, how did you solve your problem with the throttle arm on the engine?

The throttle control for our Yanmar on our Edson column has an adjustment screw inside to vary the resistance. However, it has to be set with a lot of resistance to keep the throttle from creeping down on its own. So, I don't consider the difficulty moving it as a problem so much as a solution.

I have a 2GM20F and the throttle is perfectly fine.
I have never had a problem so there must be a solution.

question about yanmar throttle...

on a Pearson 303 with an Edson Pedestal, in order to "go" i have to hold the throttle all the way forward, it won't stick by itself, unless I tie a rope around it. How can I fix this?

[norsearayder]

tighten the brake screw to increase drag on cable to hold her open ,loosen the screw if friction is too much.dont forget to tighten lock nut after adjustment

[rpearlberg]

is the brake screw near the engine, or in the pedestal where the lever connects?
