I just purchased a used QQ Yak which included a used OS Max 1.60 that is in fairly good condition but it needs bearings so I'm going to attempt putting them in. It also has a muffler that is in pretty sorry condition on the outside.

I heard from a guy in our club that soaking an engine and parts in antifreeze in a heated crockpot will clean parts like new. Has anyone had experience doing this? I'm going to go out and get a cheapy used crock somewhere and try it.

What temperature and how long do you soak for generally?

Is there a better method? I've heard dawn power disolve works wonders too.

Thanks.
