yep, lots of loose carbon.. Looks like carbon????
I have a TON of questions, but I will start with a simple one: what is the easiest way to clean BIG greasy, oily, dirt encrusted items like the bell housing, or skid plates etc... Parts washer? Sand blaster?
One more question: I was able to get the crank pulley nut off - is a puller req'd for the pulley itself?
i use diesel fluid in my parts washer, but i've also found the solvent used in flywheel turning machines kicks butt too, but will eat your fingernails and leave your skin feeling creepily sticky
the pulley sometimes will be stubborn enough that a puller may be required, but can often be manhandled off.
