Re: 9.5hp carb needle adjustment knob tricks?

[frankr]

quote Mumbles:

There should be a retaining spring pulling the flexible shaft down towards the lower cowling. If this spring is unhooked before adjusting the mixture, the flexible shaft will straighten out and the knob will stick out the front of the motor about an inch making it easy to do the adjustment. If the spring is left hooked up, it takes excessive force to turn the knob resulting in damaged knobs. Once the adjustment has been made, the spring gets hooked up again so the needle won’t vibrate out of adjustment while allowing a small amount of adjustment to be made without having to undo it again.

Interesting, I never tried that. However, there is an E-ring retainer (203470) behind the panel that prevents the needle shaft from extending out the front. Do you remove that too?
