Miss understood on the power heads sorry.
These things make us lose hair. How about this it just goes FAT? Cross flow pretty simple on Model 2 strokes I have seen the sleeve be installed backwards and gives you just what you have. But your sleeves are made into the block correct? What was the oil % the engine was built to run on? I think I would try it as nothing could get hurt. One other thing FREE revving will not show up an ignition problem under load. I have been there too.
I am glad these engine are fun and not brain surgeries.
All we need is 1. compression, 2. air mixed correctly with a fuel and 3. good spark
