What you see is the oil used for protection that makes it look rough inside. Believe me, it's all polished,

Even though it has an O-ring to seal the back plate, I may seal it with RTV as well.

First off, I'll seal the carburetor.

I pull the carb, pinch bolt, and O-ring off

I carefully RTV where the O-ring will go. It's looks like a lot on there but it really isn't.

Now I put the O-ring on.

This really isn't needed and I'll show you why later, but I put a very thin layer on the pinch bolt.

Here it is pushed into place.

I do like to seal this end.

Now I seal this end too after the carb is seated and pinch bolt tight. (but not to tight) This is why RTV isn't realy needed on the bolt itself.

Now that's sealed!!!! :-)

This is another part that really doesn't need sealed on the brand of carb, but I do it anyway.

Here's the dust boot installed and sealed.

Now the linkage is back together.

Time to seal the banjo fitting. Again, it looks like I'm using a lot, but I'm realy not. Be very carefull not to get the RTV in the fuel inlet holes!!

Do not over tighten this area, it's easy to crack the fitting and the RTV makes sure it's sealed. I used a little more then I like so I'll redo this.

Done!!! There's a work of art.

Looking good!!!

Looking really good!!!

This engine is going to rock!!!!

The backplate is another area that does not need to be sealed due to the O-ring and the quality of the Novarossi engines, but I did anyway.

As you can see, I barely have any RTV on it at all and Zero RTV inside the crankcase.

There's a perfect engine!!! I guarantee you there's not even a stray fiber in this engine!!! Yup, I'm anal about my engines!!!
