Time is the only issue, he has a lot of work coming in so he doesn't know when he would be free to do. I'm gonna put it together myself and if I run into any issues or am not sure what to do I will just take it in to him.

There an easy engine to build, just follow the manual and it will be fine.

I'm going to order a new governor cross shaft and bushing, along with a new pto bearing. Once I get the governor parts in, I'm gonna start on the rebuild, thanks for the help so far guys, definitely appreciate it.

Bocephus, I might want the name of that machine shop. I live near KCMO, but haven't found a place to do some machine work. Thanks.

I took mine to precison machine here in Jeff city. I'm sure there's lots of machine shops in and around kc. Just do some research I'm sure you'll find a good one!

I was reading the Kohler service manual regarding the crankshaft. I remembered pulling the basket pulley off required no effort and it seemed loose going side to side on the shaft. The flywheel side looks good but the pto side looks like it's damaged. Here's a pic, the area where the key slot is wider it also seems that the shaft is worn narrower there.

Here's a pic of the whole shaft. Btw I had the journal inspected just not the key way.

you can do 1 of 3 things. get a different crank, have another keyway cut 180 deg. from the original or build it up with jb weld and hope for the best

I might just pull the crank out of my other engine and get it checked out. The actual shaft looks like it's worn/ skinnier at the point where the keyway is damaged than the rest of the shaft, if I choose to get another keyway cut, I'm thinking that may be an issue right? Looking at it more closely at the point where the keyway is damaged, along the circumference of the shaft there are what I'd say are ridges. Here's a pic of that. I'm thinking I'm probably better off pulling the crank off my other engine at this point just to be on the safe side.

very possible. you could mike it out see how bad its worn. the most reliable would be another good crank.
