Having confused all you helpful people out there and myself included!
I thought best If I started again with a new post,all being my fault.
Right,let’s start again.
I have fitted a 1275 Ital engine in my Minor with an SU HIF 38 carb.This carb. is fitted with a ADS needle,this set up I have since learned came from a lean burn 998 Metro.
So totally unsuitable for my application.
Question is, which needle do I require?
Many thanks for all your patience!
Martin.
SU HIF38

Re: SU HIF38
Someone with more knowledge than me will be along soon, but my 1275 Trav seems happy with its HS4carb and standard needle.

Re: SU HIF38
Looking at Minispares, seems you may want an AAM needle.

Re: SU HIF38
Whichever needle you decide on, I would ditch the ram pipe, it will be noisy. I did try a cone filter but that still got on my nerves so I ended up with a 1800 air filter fitted to the original carb to filter plate.
Re: SU HIF38
A Mini airbox with a K&N element flows well and is nice and quiet. You will need the carb inlet elbow as well to fit the Mini filter box.
I would agree the AAM would be a good starting point. I have an AAA fitted to my traveller which has a 12G940 head, HS4 with a Minispares alloy inlet manifold and Midget exhaust manifold. It's a 1098 but goes well and the needle seems about right, the AAM is a little richer from mid to top end so should suit the 1275 engine.
Enter the needles on here and you will see the comparison
