Merry Christmas everybody!  So this has been happening ever since I've owned the car - while I'm driving, anything in between a "tiny bit of throttle" and "foot to the floor" is just bogged down.  Like if I give it half throttle it sputters and jumps.  I thought maybe it was running really rich so I checked the spark plugs, but they look normal to me.  My guess is that its a carb/tuning problem, but I'm no good with SU carbs haha.  It's a 1981 Clubman 1275GT with I think an HIF44.  Thanks for the help!

Lol, , you have owned an Innocenti, now you have a 1275GT & you say you are no good with SU Carbs. How have you stayed on the road? 

 

Try this link - http://sucarb.co.uk/...r-tuning-single - it really is simple.

 

If you decide that you don't have a HIF then look up other carbs on the SU www site.

One quick thing to check is that you have the correct light weight oil in the dash pot. It does sound like a mixture problem to me.

[slidehammer]

Have you checked the dash pot has the correct amount an type of oil in it? - sorry repeated myself here didn't the first post went!

I checked the dashpot and it has oil in it.  I did some research and confirmed that its an HIF44.  I tuned it back to run lean and it still sputters at half throttle and I hardly even accelerate.  I've attached a picture of my coil and my distributor.  Does anyone see anything wrong with them?  Also, in the distributor picture, what is the plug with a red circle around it supposed to be connected to?  Thank you!

 

P.S.  The Innocenti's carb ran perfect and I never had to touch it haha

The plug you marked is connected to the oil filter head so pressure sensor?

Doesn't look to be a connection(for a pressure switch) there to me.... It would be in the usual position

A quick check I use, does the car have a rev counter fitted? If so all you do is::

Get the car to give the fault, hold the pedal steady...

Does the gauge 'spike' by 500rpm then settle?(electrics related, possibly coil so I'd swap for a known working unit)
Or

Does the gauge stay cosistant in readout?(fuelling related)

I have a new dash and 3 gauge cluster with a tach that I haven't yet installed, so right now it doesn't have a tach     I think I've narrowed it down to a distributor/timing problem.

You'd be best to double check by wiring in the rev counter, I don't know about earlier cars, however my 1989 onwards minis have the wiring in place in the loom

Just a quick thought. 40 years ago I had a Clubman (1098 - I think), that had issues like you are describing. I faffed around with the carb, took it out for a test, no better, faffed even more, still no change. In the end I took it to a Leyland garage & the simple, quick remedy was to change the condenser in the distributor..

Just a thought, but a relatively cheap thing to change & check.

Good luck.

SO.  I tried as many things as I could before I threw in the towel and took it to a shop...  I bring it to the shop (which specializes in old British cars and other imports) and drop it off, expecting it to be an easy fix for them seeing as thats what they specialize in.  I call multiple times throughout the week to see how its going, and they said they were waiting on a part since they got the wrong one.  The only call I got from them was to pick it up, so off I went.  I arrived at the shop and they explained that it was a AAA needle (waaaaay too rich) and that I actually had the wrong carb for the car, and that it was a HIF 38.  Reminder - they never called me and told me any of this, because at this point I would have just bought the right carb.  I say alright whatever and go to pay.  This is where I get the real shock...

 

 

 

$700.00 (£565.75)

 

 

They say it was labor costs but labor cost my ***..  Not too pleased as you can tell lol   

[Scousemouse]

Most of that "LABOUR CHARGE" is pure bunk,how'd they can charge you for labour when they told you they were "waiting on a part" because THEY ordered the wrong one.

Probably nowt you can do but...never use em again and put the word around how they RIPPED YA OFF!!

[Dusky]

O hope for that price they bought a new carbs?
