I have just reinstalled an EZ30R timing chain using the factory service manual. When installing the RH chain (pistons 1 3 5), you have to align the blue chain link with the LH chain on the lower idler sprocket. The problem is that even though I have done this and followed everything properly, the RH chain slacks out at a point during rotation when turned over by hand, then regains tension. Is this normal? The engine is currently on a stand and isn't full of oil.
