    Welcome to GH. Compression test (not with your finger). You might have seized it.

    correct 150 150 60 are compression psi in the cylinders ... guess ill b pulling it apart later this afternoon .. What pistons does every use in thease things. Im not sure what im going to do until i see what the jug looks like ... if its a mess , then its time to build a killer.... or if it can just use a hone ill put a top end and build the killer in the winter and enjoy it for 2 more months..
