Carb or brake cleaner will work fine. 
 
Carb cleaner is a bit stronger.
 
A toothbrush will also hasten cleaning the accessible, really tough spots..

" i down to combustion chamber cleaning".  Are you referring to the combustion chamber itself?
 
If so, get the piston TDC (compression stroke if a 4 stroke), and let it soak with Sea Foam for a couple of days..
