[QUOTE="Reelized, post: 423606, member: 2163"] If the picture I posted looks like your linkage,the part I circled should move forward after about half throttle. Do the same test again and see if you can push the arm connected to the bar i circled forward.It should move freely.If that arm that connects under the flywheel is in the same position from idle to full throttle position you are not advancing the timing. Yes you can do this with the engine off. I would get a service manual and it should explain the sequence of the throttle and timing. [/QUOTE]
