Has anyone tried fitting this without the spacer? I realise the spacer is designed to disperse heat coming from manifold but also make space for the choke assembled plate and throttle movement but didn't know if it was vital?
Could do with finding another few mm to fit carb and air filter....!

If you don't you will find the carb will not work.

Fit a longer top stabiliser bar. Or adjustable one.

I used a spacer off another car, IIRC it was 1/4" thick off an MGB - worked perfectly. Gave a bit extra room and still isolated the carb. I had it on a 1340 with an HIF44 in my Clubman Estate.

The throttle lever will also jam on the manifold without a spacer, though you can usually fit a thinner spacer.

I don't have the spacer on ours - the combination of air filter, manifold, engine and subframe made space a little tight against the bulkhead.

 

I had to trim the throttle pulley/lever slightly and file a small area on the manifold, no major changes. I'd prefer to use one to keep a little heat out of the carb but so far I've not really noticed any issues even when driving on very hot days.

I know they are supposed to be a heat insulator, but really,,,,,,,  I doubt you'd have problems with heat transfer here,,,,,,

Yes got adjustable steady ready to fit, just prepping for 1275 install. I'll mock everything up to see if anything fouls and mod what I need to, sounds like heat isn't an issue for some so that should be ok.
Thanks as ever for input

Hi sorry to chip in but what material can I use to make a spacer for a HIFF44 carb?

[Turbo Phil]

It’s phenolic plastic.

You can make one out of just about anything you want.

 

BUT the originals are, as phil says, made from an insulating material. 
 

early spacers on the HS carbs were alloy but were also changed to Phenolic plastic.
