Hi .
I have a question i hope you can help me with.
When im starting my engine cold i would like to rev the engine a little. But when i move throttle without putting gear in nothing happens when i turn the key
Before i could rev the engine when starting.
What i have to do now is when the engine is cold i adjust the Isle screw to add more preload on the wire. Then turn back screw to adjust idle.
When engine is started i have no problem to rev it without putting it in gear.

I guess there is a microswitch somewhere that need to be replaced.
Any idea how?
Or can i just bypass it?

Press in on the button in the middle of your throttle/shifter control arm while advancing the lever. That should disconnect the gear shifter but keep the throttle connected.
If that still doesn't work, it sounds like you'll need to do some troubleshooting on the control mechanism.

The neutral safety switch is inside the throttle control, so it's out of adjustment, loose or needs replaced. It can be bypassed easy enough but would not recommend it. Just think you move the handle forward and you think it's in neutral but its not
