You can adjust the fast idle speed by adjusting the slack in the throttle cable with the adjuster on the throttle housing. Less slack will increase it, more will reduce it. Mine runs at about 1200rpm on the button, not a lot above tickover but just enough to let it start. I've found that if the fuelling is set up correctly, it won't usually start from cold without the button. Especially in our climate. If it does, then it's probably a little rich?? |
