Thanks w8ye. I will order from Frank. I'm guessing that this little Enya has either had a-lot of use or was run very lean on oil. Surprisingly the main bearings are in good shape but they will survive on very little oil anyway. The engine makes a click when the toe of the cam approaches the follower and another click on the tappets ride down the backside of the lobe. I suspect loose manufacturing gear lash to be the culprit as spur gears seldom, if ever, wear out. I'm hoping the loose gear lash will be of little importance when the engine is running at speed.

Thanks again,
Bill
