How bad is this gasket installation

Can I see a picture of where the cylinder goes in relation to that intake? I think you have to trim that protruding part off.

To me it looks like the bolt did not even go thru the bolt hole in the gasket.
I can see the gasket totally missed one bolt
The square tab part hanging out, I assume ya just cut that off, it's just there to hold the gasket together for assembly
Maybe ya put the gasket in backwards/upside down. because it sure isn't lining up the way ya got it now
If that gasket really don't line up and it's the wrong gasket, ya got 3 options
1) Get the right gasket
2) Make a gasket
3) Use gasket maker, don't try and use the wrong gasket, just use gasket maker

I had to look very closely and expand the pic to identify the spot you questioned.
The right thing to do is figure out why the misalignment happened....as Wrench suggested. The problem with that missing piece is the cases' machined surfaces will not touch each other where the gasket is missing even after the case bolts are tight. Sealer alone probably.....could...or will get blown out from that spot. Sealer may or may not hold but...., why take the chance?
When assembling engine cases it's a good idea to clean the machined surfaces well with something like acetone and be sure nothing touches those surfaces after cleaning except a new, clean gasket OR sealer like motoseal, Or both...depending on your preference.
I've heard of people coating the gasket and surfaces with engine oil because oil will get to it from inside. I prefer the method above. I rather have clean case surfaces and gasket.
The last thing you want to happen is go through all the necessary work of assembling an engine, mounting it, alignment, support cables, etc then running it only to find the bad gasket spot(s) leak. Then you have to break it all down and start over.

Before I install the gasket I cleaned the surfaces then wipe that would break cleaner. When I installed the crank case with the crankshaft installer tool I didn't pay enough attention to make sure everything lines up. You guys think I can just loosen up the case enough for me to push the gasket the right way or do I have to redo it completely with new gasket

If it were me, being a 2 stroke. I definitely would split the case halves & replace the gasket. When you get a new gasket, trace it on a pop box or a cereal box for a template to make your own gasket.

I like coating gaskets with the appropriate silicon type sealant. Talking a thin wipe over the gasket, no extra. It helps to keep gasket in place and to seal it. Only exception is cork. Silicone is too slippery and the gasket will move when tightening. Good glue type like permatex is better for cork gaskets, light coating, no excess.

I have a Toro 22” mower that had this same problem. The gasket didn’t match the case. A bolt hole shaped piece of gasket stuck out of the case.
Someone gave it to me because it leaked oil bad from the missing gasket spot. It didn’t start leaking on the owner until long after purchase.
I ordered a new case gasket with the correct Koehler engine model and got the same wrong gasket that was in the engine when it was purchased at home depot.
I pieced the missing spot in with same type gasket paper and coated both sides of cases with Indian head gasket compound. It hasn’t leaked since.
It’s a good sealer for stuff like this but it can be a mess to work with if you’re not careful applying.
