Shindawa LE230 engine repair

[aidank]

Was donated a perfect condition hedge trimmer this afternoon which wont start.  Its 25yrs old, just doing 5hrs a year with it for myself.  Always was a good starter until yesterday, when it wont fire up.  

 

Test as follows

Fuel Good

Spark Good

 

Exhaust Removal - Piston is scored............now i  know why it wont start, It has come compression I guess as it pulls a good bit stiffer with spark plug in than out.  It gave a roar once for 2 seconds while i was attempting to start it. 

 

Its in perfect condition, thus I think its worth an engine rebuild.

 

Where would I source a kit for it
