Is there anybody out there who can tell me the fastest??, easiest?? way of opening up a blocked 2-stroke exhaust system??

I am rebuilding an old 185 2-stroke Suzuki and came across this problem.  Without the exhaust the engine is 100% but replacing it, the engine does not idle or rev.  There is no other obstruction.  I suppose it is a matter of old oil and carbon buildup.

Thks a lot.
