couple of things ive learnt
1- the oil pressure gauge showing low - you can always take it off and spray carb cleaner into it to help clean its internals and see if it makes a difference although putting a mechanical gauge in there to test oil pressure will ease your mind
2- slight stumble at idle - definitely check for vacuum leaks in the little hoses but also put new spark plugs in to eliminate them - who knows how old they are
