Found cranks.  :P  I search just a little harder when it is posted here when I look.  ;)
But I had already found them last night and couldnt find thread to let you know here.

Got a good 1

I'll trade then when I get the dolmar in hand.

I havent found a 385 390 yet.

Came across a 395 crankcase while I was toasty looking for ya. Suppose to be a good crank in it. Now to remember where. Not that it helps.

Thanks Kevin, I actually placed a big order from Nate & thought I had everything for this project last fall, before I realized everything that was wrong/missing/messed up.  I didn't want to order a 66 cent part, but looks like I am going to have to as nobody has em to trade.  Oh well

Figured out part of the hold up today for the dolmar parts. crank #2 was no good so he was pulling another crank out to send cranks together.

 Sorry for the waiting. But not in my control.

The other one I still have to take out of a case half. Case half looks good too.  So you are getting the one that is out in pics.

As long as its good, I have no problem removing from case half.  Sure can't wait to put this 1 together.  Still a chance this could hit the wood this weekend :)
