Any suggestions? I have got a head and other bits to clean, Old burnt oil, dirt and grease and carbon in the head.
I know you can send them to engineering places but i have this to do now and more in a few weeks so would like to do i my self.

Will need to soak for the hard to reach places?

 

Jizer will get most if not all. Soak in red diesel for hard to get places (if a brush can't get to them)

Jet wash or rinse with water then dry with pressured air.

 

lots of places now sell them parrafin washer things so yuo can clean your parts yourself

think they are about Ł40

 

stick it in dishwasher
