I don't know if this helps but model: 928988A
Could this problem be caused by bad coils? I have been following the Kawasaki thread, and although this engine is kohler it seems to have similar symptoms.
Secondly what exactly does a black Gunky spark plug signify? Oil seeping past spent oil rings into combustion chamber, worn valve guides?
If that ends up being the problem, how difficult is it to replace the guides? Does it involve removing the head and replacing the gaskets as well? Thanks
