the ecm does a terrible job in the 1200-1500 rpm area for advancing timing for good MPG, load is too high at 55-65 mph for the stock timing to be high enough.     flip to lvl0 and watch what timing does.  

 

 

under 1200 rpm there is no light timing advance as well.

 

 

mor ethoughts as well,  it is not timing causing the bucking.  It is a fight between the ecm and the quad with the fueling messages.  The ecm starts sending high prorirt fueling messages at super low rpms when it thinks that the engine is at risk of stalling.  

 

the ecm sends a bump in fueling that gets mixed in with the quad's reduced fueling causing the bucking.

So in laymans  terms it’s not possible for them to coexist smoothly below 1500?

Here are 2 tools that work quite nicely:

 

Lang 87 (USA made) and ATD 4031M (Taiwan, but well made)

 

In the pictures the blue handled one is the ATD.  I prefer the Lang, but they both will remove and install an HX35 snap ring(HX35 snap ring in pictures).

I would like to thank @Joe_Poolfor the info on toold. Picked up the Lang and it looks very suited to the job,

Dripley, you made an excellent choice.  Gotta love the Made in USA!

 

Note:  Loctite the silver tip on the lead screw, I have had them "walk" off occasionally.
