That's a fairly common 'rookie' mistake so don't feel too bad
The engine should be fine, especially if it was assembled with adequate assembly lube.
you can see where the grooves should line up..... make sure the male end is pushed all the way in as far as you can, then align the teeth on the clip with the indents on the insert. Once the clip is in, hold the end on the frame to brace it and try to pull the end going to the engine back out. Sometimes it's easier to get at them from underneath.
To effectively prime the system, pull the EGI fuse. It's located at the fuse box near the battery, middle fuse.... look on the cover. It's a pink 30 amp fuse.
