I've NEVER had this thing adjusted correctly, have owned it for 12ish years. Came to me with everything out of spec. Every once in a while I try to adjust it correctly and fail. Another attempt the last few days. It's a remote shift, and the procedure is a bit different than the side/tiller shifts. Here's what I'm doing (picture attached for reference).
1. Disconnect throttle cable
2. Move lever "A" aft until lever hits stop
3. Adjust idle screw until idle cam follower makes contact with idle cam (arrow), then 1 turn in
4. Move "A" forward to WOT until it hits stop. Adjust shift lever "B" so that throttle opens completely.
When I do this and I'm in neutral, "C" and "D" have no aft preload on them, so the throttle doesn't always close all the way, and "C" doesn't return to the timing stop (so timing remains advanced, throttle doesn't close, idle very high). It seems that this isn't solvable unless the throttle cable had more travel. Hoping someone can tell me what/if I'm doing something wrong here.
Timing stuff:
Have a fancy light and cheap HF light. After years of trying to time this thing, I finally realized that using the advance timing feature leads to inaccurate results on a 2 stroke. Also, even though the Bosch light has a 2 stroke feature, the RPMs show double what they are until over 5k. Reflective laser tach also shows double, which I don't get at all. On cylinder #2 the rpms are accurate. I'm getting 5500 at WOT with timing at ~23' at around 3500 rpm. Don't know if an extra 2' of advance will make a difference?
