decompression lever stuck

having a heck of a time getting my 550 to start, it only starts if i shoot starter fluid into the air box.

someone suggested to me today to check my decompresison pin. I wasn’t able to move the lever at all, it was completely frozen.

I took the 2 bolts out and removed the decompression assembly, but the pin fell into the camshaft. so now i have to figure out how to get it out. i’m guessing i have to pull the cam out to find the pin?

anyone ever have this lever be seized? and what sypmotoms did it cause?
