Carb spacer question

[Hap Waldrop]

I building a set of carbs for a 65 Mini customer, he bought his own parts and sent me the parts and carbs, he has these new spacers that have nipples on them for hooking a line, I'm kinda baffled, because he has early model HS2 carbs with port vaccum on the one carb and I can't think of any other reason for the hose nipples, it all came in Mini Spares boxes, I fiquired maybe this was intend for a later car to switich it to ported vaccum. Any thoughts????

Hello Hap,

I seem to recall a long time ago that such an item was used to attach a vacuum gauge, so as to avoid having to drill and tap the manifold? Not certain though as it was a long time.

What Alec says would make sense. Those vacuum gauges were a very popular addition at one time.

As stated above, the nipples are for an aftermarket vacuum gauge. I'm glad to see they're available again. The spacers were NLA for a while.

I run a vacuum gauge and since those spacers were not available at the time I restored my car I made a "T" fitting to tap into the brake servo manifold connection.

Maybe you could use it for nitrous injection. /bcforum/images/%%GRAEMLIN_URL%%/jester.gif
