Complete disassembly, clean the parts in a parts-washer, follow up with compressed air, lastly generously oil each part and wrap in newspaper or shop-rags. Then set aside until ready for reassembly.

It's a lot process, but the only way to ensure there is no grit left inside that may destroy you engine. This will also give you a chance to inspect for damage caused my dirt getting in!!!

How did the engine get full of dirt? Did some one swamp it or something?

Can use diesel fuel or kero to flush it out. I agree to pull it all apart to clean and inspect but not much details to how, where or why there is dirt in it.

No I bought the engine with no top end on it but the guy always had It was stored indoors he just never put a rag in the top of the engine to keep it clean
