I tried to find a link last night to post for tattguy12 and the only one I could find is this one, which does not show all.

And this is what most use to seal engines.

You can get the sealer at most auto parts stores and places like Wal-Mart.
Places to sea.
Backing pale of the motor the one when you take the plate off you can see the crank and rod.
Carb where it goes in to the block.
Carb pinch bolt and some times the high speed needle housing.
Do not use too much and make sure you do not get any in the engine or where it should not be. If I can find a link I will post it.
