This chain is a Elgin unit with Morse chain I bought for 10$ on E Bay years ago.
Its the tightest one so far. You can push it in only 1/8".

I have Cloyes std length, 9 key way deal sowing up tomorrow. Its their best set with the "Z" German chain. So we will see where it ends up, but I doubt it can be muchtighter than the Morse chain.

So far the stock type with Morse chain is the tightest and that is why I am interested in the offset keys.
Its like I am in-between a std chain and a "short" chain. A Milodon single idler gear drive would get me where I want but it requires some block drilling and tapping and the crank, rods and pistons are installed. And 450$.
