Hey guys, Just wanted to stop back in and say thanks to the help that I got here, the 631 is up and running! The problem ended up being the stripped drive yoke. Replaced it with a new one that I lucked into, and all of the drive problems disappeared. And it runs very strong and even on both...

At the risk of getting kicked of of this forum due to pure ignorance....what am I missing getting this engine to slide back far enough to get the coupler to slide off of the splines of the hydro? We fought it for about 2 hours today, and got nothing but dirty and mad. Does the plate that the...
