ok im a engine newbie. im trying to put in the upper insert. i have gotten it this far. what do i do next? any help is greatly appreciated!

and what im inserting
Much like sex, lube it up (vaseline or wheel bearing grease works) and put in the proper place

It may take some finagling.
^^ yup.
That upper rubber part in the picture comes out.
Then you place the red insert inside.
Get some lube action going.
Then start to slide in the upper rubber part back.
Get it colse enough to get the screws back in, then start to screw it down.
The rest should work itself out.

Remember....syringes go in the RED waste basket.
hahaha thanks guys i finally got it.
