Take some pics of each side (open) so that we can see the parts etc that you mean

The governor gear is on the very top of the crank case cover IIRC;
so when you reassemble it,
you can turn it with your finger for the gear teeth to mesh.

but usually it's a very small offset only,
so with the crank already in the bearing
you can just rotate the crank case cover until the gears mesh,
push in a hair more (to ensure the meshing teeth),
then rotate the crankcase cover to line the bolt holes up again.

If you do not talk about the gear mesh at all...
I need some more explanation on what you are trying to line up.

Yes it was gear mesh, I just gave up after a while, now I eventually was able to get the crank cover to slide all the way on. Now when I start the engine it doesn’t seem to kick in whatsoever, and this was with no load so it should have reached its top rpm fairly quickley

What can we say..
either you broke a tooth off the governor gear,
messed something up during reassembly,
have to readjust governor setting (arm to pin, lever to throttle)
or you have messed up/forgotten something else.

Sorry but we really need pics now in order to eliminate at least some options
or be able to tell you which one it'll likely be.

PS for now: post a pic of your engine with the governor linkages exposed and visible.
and one showing how the throttle is attached in case you accidentally bypassed the governor

Ok well it turns out I did in fact cake a tooth off, thank goodness j haven’t ran it but a few minutes as it is.

How do these Subaru’s hold up to valve float, ie: flywheel rod, all the bits and pieces people say break and such all the time

Robin subaru engines are PRICEY..
and for good reason, they're really reliable..

As long as everything is in good condition
(no shot bearings, no haircracks in con rod or flywheel from an accidental drop etc..)
I'd say it's as reliable as a Honda GX.
IDK when they start floating valves.. but chances are somewhere in the same ballpark as well.

if you're not willing to take a risk, just buy a new governor gear off ebay..
it's not too expensive and if it makes you feel more confident it's worth getting for sure.

I'd take the risk and remove it,
but it's not my engine, not my responsibility... thus not my decision to make

Since I have heard they are good quality, and the engine has been well taken care of,(the family I bought it from I have known a long time and they take care of their equipment, they take every precaution)

I’m going to bet it’s safe to say that it will hold up like a gx, going of what Sid said
