OS MAX 55 clean
 

Whats the best way to clean a engine from a crashed plane that went into soft ground, nothing is broken or bent.sand went into the carb.

Strip and clean with petrol?
anything to look out for wen stripping motor and putting it back together?

Do you have an air compressor?
I had the same happen with my GMS .47. What I did is take it completely apart and hosed it down with WD-40. I used compressed air to blow all the residue out. I repeated this process until I was sure that there was no sand in the bearings, crankcase, piston, sleeve...etc.
Blow the outside of the engine off with compressed air before taking it apart especially around the o-ring at the carb, and make sure there is no sand on the o-rings when you re-assemble the engine.
This worked for me and my .47 is still my favorite engine and running strong.
Hope this helps
