UncleD.....Easy first success? The chain looked a bit dry to me, I would suggest at least enough soft low melting point grease to cover up to the top of the drive sprocket. When the engine warms up this will settle to the bottom of the compartment and lubricate the chain nicely as it passes through the soft grease. I prefer to use graphite grease rather than a plain medium grease.
The oil feed and return pipes should be armoured to give some protection against accidental abrasion, both of yours look a bit non standard. New pipes are available with the correct armour and end fittings.
A characteristic of these engines is a tendency for oil to accumulate in the sump, due to infrequent use, this is termed "wet sumping", resulting in lots of smoke on first start up. This smoke clears as the oil pump scavenges the sump. There is a gauze filter in the sump, well worth taking the sump plate off and making sure it is clean, as a clogged filter here will affect the scavenge side of the lubrication system. Lots of help in previous posts on this forum.
