I think I know what did it...
I couldn't find good info on the right oil mixture before so I took the previous owner at his word and used 50:1
turns out they didn't start reccomending 50:1 till 63.
would there be any harm in adding more oil, draining the fuel line, emptying the filter bowl and trying to start it repriming with the new mixture?

It won't hurt a thing, however, I would recommend a compression test before dumping any money or frustration into it. Turning it over by hand isn't a good enough compression test. It has to be at or near 100 PSI for it to run properly.
Less than 100 PSI and it may run, but won't run right and you'll be chasing your tail trying to find out what's wrong with it.
I don't remember off the top of my head, but this model (running 25:1 ratio) may have a type of "plain bearing" crank. If the crank journal is scored (from low lube) it can't seal the cylinders from one another and again, you'll be chasing your tail. This won't show up on a compression test.
Sometimes the compression will show good, but scoring in the cylinders will screw you. You may not see the scoring unless you remove the exhaust cover and inspect the cyls thouroughly.
I hate to be harping on the compression, but I've seen too many engines people waste time and money throwing parts at that won't ever run right because of compression or crankcase leaks.
