My point is you shouldn't need to do that, at least get co checked

could be mixture set weak to get through mot...

Mixture is always tweaked lean for MOT purposes and then brought back up to usable levels. Dashpot is topped up with 3-in-1.

 

As said by SiC the first half of the choke travel just operates the throttle linkage to give a fast idle, it doesn't adjust the mixture. Driving the car with the choke fully out when it's up to temp 'causes it to splutter and bog down under acceleration and cough out smoke.

I did buy a new fuel pump a while ago as I suspected the original might be tired but it was DOA so I refitted the old one. I'm tempted to go electric for reliabilitys sake.

 

 

Interesting peeps should mention the ignition timing/HGF for the Acclaim. I've not actually checked the ignition timing at all, I set the 1300 by ear as I lack a strobe light and am disinclined to try the same trick with the Acclaim lest I loose a functional car! Apparently the vacuum operated advance/retard can be a shit and is best disabled and the timing retarded a bit to compensate, not sure if that's been done already on my car.

 

As for HGF the car does seem to use a little bit of coolant and the coolant that is in it looks like shite, inside the expansion tank is decidedly gunky, the oil cap can sometimes be a bit mayoish. The exhaust also leaks water out of every join although this could just be condensation. I've been monitoring it since I bought the car and it's never been particularly noticeable in it's use of coolant although it is very much a possibility!

Didn't know that the half choke on SU was just a fast idle. My idle is to high on my Reliant but the adjustment screw seems to do very little. I am sure its more user error that anything else.

Tight choke cable will do that.

Does the dashpot in the SU not take 20w50 rather than 3in1.

Only asking as I know Squire Dawson used oil in the dashpot on the Oxford su and it seems a relatively happy camper..

I used atf or an sae20 oil. 3 in 1 seems a little thin for dash pot duties likewise 20-50 a little too viscous.

These might help you, found a carburettor manual in bottom of my tool box. Also don't these have a ballast resistor on coil to help spark when cranking

Read up on it when I first got the car and it seems there is no definitive answer, most folks seems to use the same oil they put in the engine as it is handiest. I use 3-in-1 because it's easy to get it in there! That should only make a difference when accelerating though as the viscosity of the oil will change the rate that the piston dampens at, at idle the piston is stationary so it shouldn't make any difference to the running.

Retard the timing, take some flattering pics and fuck it off down the road. That thing will never be any good. Try pissing into the wind and you'll get the idea.

Don't acclaims have some kind of rubber mount between the manifold and carb(s) that perishes? Or am I thinking of something else?

Dolomite 1850s deffo do, as mine fell to bits, twice. I shelled out for some nice alloy ones from the owners club in the name of longevity and then gave away the car... Not sure on the Acclaim, you need to take off the airbox to get a proper look at the carbs and I've not yet been arsed.

 

I really can't be arsed now as I just tried to drive to a breakers yard in Renfrew to get some calipers for the Civic and between my phone's satnav deciding it didn't want to work, me getting lost and the traffic being utterly shit it took 45 mins to do 5 miles by which time the place was closed and I was still 2 miles away so I gave up and spent another 25mins to drive 5 miles home...

Sounds like an utter shite afternoon.

 

To me it sounds like the acclaim is running weak so maybe richen the mix up a tad. Does it run on?

I may* have mentioned this already...☺

They are probably perished. It's the first thing to check on these.

Not sure if I mentioned it, but I really enjoyed your vids. I drive that road to work through Milton of Campsie and don't fancy breaking down at that wee junction!

I must be nearby and if a gang is ever arranged to keep one of these steeds on the road I'd be happy to help out with tea or manual labour.

Popped the air filter off the Acclaim to get a look at the carbs today.

 

Somebody has been there before because the airbox was only held on by the top nuts, the weird, hard to access, one down the bottom was already undone. Couldn't find anything immediately amiss, the carb mounts look to be in good shape, almost like they've been replaced fairly recently. Spraying Easy-Start in the general area with the car running showed no change so I don't suspect and air leak. I had a wee poke around the vacuum hoses as well, which also achieved nothing. One thing I did notice was that when I operated the throttle cable one carb seemed to generate considerably more induction noise than the other, I think I need to get a carb balancer on it!

 

I also de-tinted the sidelights/indicators, because priorities:

37400860_10217154301748851_3764115007571230720_o.jpg

 

I went to a local breakers yard to liberate some rear calipers for the Civic t'other day only to find that their car had rear drums but 4-stud wheels the same as mine. Oddly very few places actually seem to have mk7 Civics on site, I am guessing most of them just get weighed in...

3 in-one is, or at least used to be vegetable based and can form a ring of jelly in dashpots. I would be checking that the piston can move freely.

Twin carbs are great when set up right. A complete bastard when they're out of sync. Twin-choke Weber conversion? :D

I could never get my 1850's twin SUs properly sorted, it'd pick an idle speed at random every time I came to a halt...

 

No SUs on the Acclaim though, they are obsolete Keihins with innards made of unobtanium. ;)

Works a treat. The trick is to hold the pipe the same distance from each carb when you do it.
