Project Rusty Triumphs in Scotland - A diversion from automotive tat - 31/01/2025

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.

[lanciamatt]

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

[Guest Hooli]

I always used 20w50 in SUs too.

[captain_70s]

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

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.

[The Reverend Bluejeans]

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.

[dozeydustman]

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

[captain_70s]

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...

[dozeydustman]

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?

[D Spares & Tyres]

I may* have mentioned this already...☺

 

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

[davehedgehog31]

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.

[captain_70s]

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:

 

 

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...

[SiC]

Stick a pipe to your ear and the other end in each carb.

FTFY

[Richard]

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.

[dozeydustman]

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

[oldcars]

Twin SU's. christ i can't even get one right let alone two.

[captain_70s]

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.

[captain_70s]

If you can't drive it fast at the moment, at least it can look good going slow

 

Oh, that reminds me! I forgot the most important thing, I bought a key fob of the cheap eBay variety!

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

[captain_70s]

Listened to the carbs with a length of hose, they sound about the same to me. Will try to do valve timings soon. Here is the sound of noises:

 

 

I also fitted this quality NOS Unisef radio cassette courtesy of AS user Aston Martin:

 

 

I did eventually get the cassette player to play quite loudly through the left hand channel by repeatedly ejecting/replacing the tape... The right hand channel is still very quiet.

^ You need to adjust the tape-head height using a miniature screwdriver. Possibly accessible through the slot the tape goes in. Trial and error, could be fixed and totally transformed in about 2 minutes tho. Tiny screwdriver like one you'd use to fix spectacles with, or sometimes get out of a Christmas cracker.

Reminds me of 1988.

That's what I thought!

Never seen one like that. Every bastard one I've had to do involved pulling the deck out.

 

Either way it opens the opportunity to say tape head azimuth

[JeeExEll]

^ I meant getting to the screw for the head-position at an angle. Prop the little door open and shine a torch in. Sometimes possible and saves taking unit out.

Reminds me of cleaning tape-heads with cotton-buds and cleaning-alcohol or cleaning-vinegar.

 

Otherwise, sometimes possible to pull the unit out far enough to remove the lid and adjust the head whilst all still connected in the car.

[Squire_Dawson]

Good work. A good stereo makes all the difference on a long drive.

[M'coli]

The tape head could just need cleaning. If you can't get a cleaning tape or a damp cotton bud, I usually just lick the tape itself, wind it back a bit, slot it back in and let it play. Unsophisticated but does the trick...

[captain_70s]

Cannae see any adjustable bits chaps...

[M'coli]

That's a lid-off job to adjust the tape head. You could probably get to it to clean it though.

[davehedgehog31]

That looks neat.
