Just want you guys to be aware that some aftermarket 036 kits are not flat across top of base where bolt heads are.

This is a post and pic  from a guy trying to rebuild a 036 with AFM 036 cylinder kit that came from Northwood saw.  $89 for P+C.   

Yes it is the wrong bolts in pic, they are just being used  to show the unevenness across top of base.

(((What I was trying to show is that the surfaces that the bolt heads bear against weren't machined,
and are far from being parallel to the machined flange that mates to the crankcase .
The Torx bolts would sit in there the same way.
It's as-cast & the flange faces have about a 7 or 8 degree draft angle to them.
Even if I could torque those bolts to spec without snapping heads, they won't last long once I start cutting.)))

He is going to mill the bases flat he said and Northwood offered another cylinder kit or $25 credit on one he has.

Great site here - I have been lurking for a week or so.
Thanks for posting that, Cut4fun2. 
That's my cylinder and fat fingers in the photo. 
Will provide more details if anyone is interested.
I asked Northwood to check their inventory, as I have to believe they will be losing some customers if they sell many units like that one. 
I work with design of bolted flanges in my day job and I have to tell you that assembling what you see in the photo is a sure way to gaurantee that you'll be tearing it down again - probably soner than later.
