A word of advice....Don't do anything that you are unsure of.
Hope you get it sorted soon.

I'd rebuild the WP, clean the carb and see what you have then before doing a head gasket or other repairs. Oh yeah, check your valves, timing and cam chain as well.

Just wondering, did I miss where he said these things are good and check out on his bike? Unless I missed something I don't see anything relating to the carb in his post and this very well could be another factor why it doesn't start very well. Not saying it is it, but with the limited info he has given us unless the bike has severely overheated blown head gaskets are not that common. Also not saying head gasket not the issue, but on an older bike carbs and top end are the most common reasons starting is hard.
I can't see why the fuel would leak into the cylinder given that your float needle is not blocked ,the o-ring is okay & the float is set right. It should not be able to leak into the cylinder if all this is right.

It would depend where the head gasket blows. It has more chance of blowing through the water jacket in theory but I guess that's why there is an Drain hole on the water pump to stop that happening. Still doesn't mean that it hasn't happened though.
When I had coolant in my oil, it was a cracked cylinder. It cracked on the intake side and went down 2 inches. I had a to do all new bearings (main, balancer and trans), crank, piston, cylinder and gaskets/seals. When I had a head gasket blow I never had coolant in the oil but it was smoking a lot from the exhaust.
Also, if the oil can drain into the water & the fuel is draining into the oil that would explain why there is so much fuel in the oil/water.
I'm not saying it is the head gasket but highly likely.
