yup...turning the motor over...regardless of method...should produce a spark...I think you're right...you missed something...almost like something is wired backwards allowing current to flow to starter but ignition is killed...has to be at the ignition/start button...push that all goes to ****...pull the rope & it fires...I'd be suspect of that start button...can it be ohm'd for resistance?

My thoughts exactly that's why I changed out the starter button, kill switch assembly. What makes any difference if I pull on rope or jump the starter with another battery. Both methods only rotates the crank. Which in turn produce spark. But I'm gonna look into the neutral safety switch tonight to see if that has any effect on stuff.

what does it mean if the e starter spark is non existent (super low) but the recoil provides strong spark?

As I wrote above, it is quite common and nobody seems to have a definitive answer. I found it was the neutral wire on a Honda, Rayzar found a corroded wire from CDI to coil. As I also posted above, blipping the start button and hoping a spark will "catch" while the engine is still turning over, is what many owners end up doing.

Did you ever found the problem? I have the same problem with mine
I would highly appreciate if you share the end result of this problem.
I have a 1999 Yamaha Timberwolf 250, that I can not get started with the electric start, (starter turns motor over like it should) but will start by pulling the recoil starter. I have changed almost every electrical component there is. I started with a new battery, then I have tried 3 different stator assemblies, new cdi, new coil, now rectifier, a different wiring harness, new solenoid, and a different start/kill assembly on handle bars. The thing is when I turn over atv with starter I have an inline spark tester and showing spark, but doesn't start then I pull the recoil starter it fires up. The battery shows 12.7 volts and 11.7 while engaging the electric start. I have adjusted the valves, I've done compression check, 110psi. New plug. Also another question is, I have key switch on, and jump solenoid but does not spark. I've even tried to use a direct hot wire to starter to turn over motor and no spark, but it has spark when I use the button but doesn't start atv. I'm at wits end and would like any advise I could get.
