Hi vint_mow,
One other thing is you need to do is remove the little tube that is for the decomp hose, it pulls out with a wriggle with a pair of pliers. If you go the bore the manifold to fit the spigot, (this way it looks factory) then you have to be very careful as the o/d of the spigot is close to the max you can take out of the manifold. I make them a snug fit and put a smear of JB Weld to hold it in place. With the decomp hole I drill a bit of a countersink in the top and fill it with JB Weld as well
Another thing, don't buy a new carby, just look around and you should be able to pick up an old PT on the side of the road or get one from a tip shop. This way you get a manifold and snorkel as well because you are going to need these bits
