lets put it this way. if it is internal and you checked all your connections and have good grounds. if the motor gets tight as you have explained I'd have to say take the head off , take the pan off, you can check if it has a ACR or spark advance then and take the rod cap off to verify the journal. you may find the dipper broken off. I can only go by what you tell me. you may want to take it to someone who knows what they are doing but that's up to you. if you want to keep working on it to start it and run it the way it is at worst you can break a rod and punch a hole in the block. the main concern I have is you say it gets tight . on the K series the main failure points are the rod journal and the bore. I don't think I've ever seen a main ball bearing on the crank fail.

Well the dipper is broke off the piston is tight in the bore and the journals are a mess

dipper breaking off pretty much caused the rest of the damage. that's your lube source

Sorry to hear that. At least now you will know what you got when you're done rebuilding it.

That's what I thought the dipper was for. I can get a motor for 150 or get a rebuild kit not sure yet
