No not yet...We still cant figure it out but machine wont start without small shot of either
Sounds like an injector issue to me. had the same problem wouldnt start without a sniff, replaced injectors fixed the problem. it also had a broken wire to the maf sensor which i believe to be unrelated. the injectors are expensive, if you have means to test them id start there.

Using ether is playing with fire on these kubotas. They arent designed to handle that. Its a great way to bend a connecting rod.
