Instead of following up the specifications/adjustment values in Haynes, you'd better let the car run on 3% CO. More than 3% is too high, less is too low to let the car run properly.

An old Volvo-mechanic told me a trick he used for the B19A 300-series. First, check the level of the ATF-oil and fill if necessary. Then, let the engine run at idle (warmed-up!). Remove the upper cylinder of the carburettor (you know, that needle and screwable cover that you remove to put some ATF-oil in the carburettor), but just lift it a bit, do not completely remove it from the carburattor. Then, put the cylinder/needle and cover back. If the engine runs better when you're putting the needle back, you have to turn the CO up a bit.
It's a bit difficult to explain it in English, I could show you the trick when you're at a V3C-meeting (are you coming to the Algemene Ledenvergadering this Sunday 20th?) or in my neighbourhood (I live near Emmerich (D), just near the German border).

Ooh, I dunno - I don't think I'd get a very high "thanks to posts" ratio with my nerdy posts about OEM 80's stereos and cavity covers

That's a good piece of info Joost, cheers. I have a massive respect for carbs and try not to touch them unless I have to, so I'd be pleased if you could show me the trick I'm often in Emmerich as the wife comes from there ... I won't be at the ALV though, as we'll be in the NL in two weeks' time over the Karneval weekend.

The carb had a Volvo-main-dealer rebuild in 2005 for over 700 Euros it's running a bit lumpy on that YouTube vid, but that could be due to the Russian flat-bed truck owner overdoing it a bit on the choke. It's been fine, the few short journeys I've driven it on.

"Anmeldung" tomorrow morning ...

Cheers

The choke is nothing more than the throttle. You can feel it when you're starting: pull out the choke and you'll feel it in the pedal.
Too much choke is just more RPM's

Last year I've rebuilded the carb from my own GLS. The Zenith looks very simple but isn't, though. It needs a bit of "love" and feeling sometimes

You can always come by, when you're in Emmerich. It's 15 minutes by car to where I live (Ulft).

I've lots of information about the Zenith 175 CD2/SE, but it's all Dutch....

I don't know specifically about the B19A carbs, but that's certainly not true of the carb on my B230A (very similar). The primary function is to add a ton of extra fuel. The secondary function is to open the throttle slightly The amount it opens the throttle by (relative to the extra fuel) can be adjusted. You can hear the engine 'chug' when it's too rich...that is hard to do with throttle alone

cheers

James

It is indeed very similar, but not the same. It is hard to "chug" a 343/345 B19A with a correctly adjusted engine/carburattor.
Sometimes, I manage to 'chug' my GLS but the only thing that happens then, is a rythmical shaking car (you know, the well known chopping Harley-Davidson sound).
The solution is simple: use less choke. That also means less RPM's (and an engine running more silently ).

According to the youtube-video, it looks to me that the CO of Tom's DLS is way too high or way too low. But maybe his DLS was just bad-tempered that day

This is the video in question:

filmed at the end of 2009.

I've just fitted the plates and picked it up from the garage The first thing to do: buy a new battery. All this standing around killed it off (and no-one bothered to disconnect it at the garage )

I'm looking forward to a blast around the Siebengebirge hills tomorrow

enjoy dude!

That doesn't sound like the "rich chug" I'm used to from over-choking...just a generally rough idle. I'm sure with a little TLC that can be easily cleared up.

Enjoy tomorrow's drive

cheers

James

That was fun



















Did about 120kms today, the first real run the car's had in a year and a half ... It goes really well, torquey pull at low revs, great exhaust noise, and all feels nice and tight - not like my daily 360 with over double the mileage.

Tom

Great news and great pics, especially the last one! Nice trim rings

GR8 NUMBERPL8.

There's a surprising amount of chrome on this car; it's just the front that's purely pov spec!

Baby seats, in a 3 door, at the Nerburgring.

Tom is hardcore.
