Ok, sorry for the crappy pics, my camera is dead, so i had to scan the parts.

This is the main jet/face screw of a G4 carburettor, the plastic tube can be removed.

And this is the main jet/face screw of an LM, the plastic tube is manufactured into the post where this screw threads into, if you look down the hole, you can see it on an LM carby.

You need to have the carby that has the first one, if you get the fist one, and it wont fit into the carby, then the carby body is an LM, and not a G4.

Cheers
Ty
