Here's a bunch of pics from one side. The other head is coming off today.

I think it might be borderline rich, but no doubt things have been burning pretty good.

 

WOW! What happened?

 

Nothing .. just doing a head swap. I wanted to check up on things while it was all torn down.

I haven't found anything bad yet.

 

Just looks dirty. Running a bit rich?

What heads are you puttin on there?

 

From what I can make out it looks fine to me. If it was too rich there would be black fluffy buildup that's brown on all the high spots from getting hot. It might be a good idea to take some more pictures, only three of those have visible detail. Unfortunately none of the piston pictures came out. Try standing on a ladder to increase the focal distance, use optical zoom to bring the target into the field.

 

clean that baby out every once in a while by hitting that thing called a gas pedal!

j/k bro.
