If the oil looked new and in good shape, simply put the bottom plug back in, remove the top plug again and fill the rest of the way up with quality lube until it starts to run out. Replace upper plug and you are good to go. Check it periodically between changes via the top plug and if none runs out again, just add lube until it does.

Back again, and thanks to all for the good comments. So I got myself a service manual boy what a treat, being mechanical in nature, the book is very detailed in its explainations of setting the fuel air mixtures, idle and most of all in my case the oil pump.
I have not begun the setting procedure as it will take some time and I would like to do it over the weekend. I did do a quick inspection of the oil pump calibration and guess what its way off, the two timing marks are about 3mm apart on the rich side. I will not mess with them yet till I go through all of the setup as described in the book.
I did have a question for all the engine guru's out there, the book mentions an "idle speed screw" and an "idle stop screw" are these one and the same? They do not provide illustration for these unfortunately, I am assuming the idle stop screw is the one close to the throttle cable on the throttle arm. I would assume the idle speed screw would be some where in the carb region, otherside the roller cam?
tskm2001 - at first I thought it was raw oil leaking out of the front, now at closer inspection I realize it could be mixed with fuel and the float bowl explanation makes a ton of sense. Thanks I will research further. more

All oil hoses should be replaced every 5 years. If one breaks or cracks, catastrphic engine failure follows quickly. A wise $2.00 investment. more
