Front lever on the bottom, on the front on the idle stop. Up the top you have to have a gap. Over there you've got the throttle cam on the roller. Right here we go in the gear. As soon as that starts pulling that throttle the cam roller moves comes along to there. Now the timing starts to advance. The advances up full-time in carries on to full throttle up there. Bringing it back full throttle off. Off comes the advanced timing slightly still. That's completely away from advanced timing. The throttle still coming off on the roller right back to idle stop. That's got to be it.
