Crank journal limits on animal/wf


Hi guys, I think that I have a weird one here. I bought a new animal engine and a wf connecting rod to beef up the engine and to my surprise the rod locks onto the crankshaft due to not enough clearance. IT IS INSTALLED PROPERLY and it has enough side clearance. I tried another wf rod and it does the same. I then took the rod that came with the new animal and put it on my old crankshaft and it is way too loose. Has anyone had this issue. All parts are as they came from Briggs. I will mic things tonite, would someone post the specs for the crank and rod. Thanks
