No need, they were measured in the Samba thread - same as .2 so it's just those 4 extra holes near the middle.
Alright… Emusion : .4 Venturi : 30 Idle : 60 Main airs : 180 Mains : 125 So going from what Zed said….. my mains and venturis are not a good compatibility, so I can change either of those out…. Dicky said they got better results with the 28 venturis, but that most are running 30s… any other opinions on that? Otherwise looking good. And from samba thread it sounds like i could try soldering up the extra holes on the emulsions right?
Technically speaking the mains should be ok so it would be interesting if others related their experiences. It's just my experience that I end up with 135 mains for 30 vents which "technically" should be too rich. BUT with your .4s, all bets are off as they will provide more fuel emulsion so it might be that your setup is good to go as it is. 60 idles are IMO a bit big but no harm done and it will drive nice at low revs. So... how do you prove to yourself that all is well? 1) spend at a rolling road and hope the geezer knows what he's doing. 2) fit wideband AFR meter for about the same cost and DIY at your leisure forever.
^ me too and I'd sell you some if they weren't in the van which is away being fixed up. I've got 4 of everything and I mean everything - idles from 45-60, mains from 125-150, vents 28,30, 32, main airs from 180-240... probably spent more on jets than the carbs cost. Also will be selling AEM air/fuel meter, extended loom etc - again stuck with the van at the mo - you're too early!
If you can't wait I found The Green spark plug company are very cheap for dell bits. circa £2.70 for jets.
I'll have to check if they are genuine Dell jets but if not TBH you might as well get them from GSP Co or it's hardly worth my while posting them!
Cheers Zed but i need to get moving on it… I am in Germany most of the time, while the van is stuck in UK Did you DIY the extender loom for your AFR?
Yes I did - the barstewards wanted some silly price for a long one. I did use shrink wrapped soldered ferrules and both connections are inside the van.
Yes, you'll notice I left them off the list. I'm running 32's because I have the big sucky engine and even so 30's were not that different.
sorry Zed but I cańt make any sense of this…. If i remember right on my solex setup i had a rubber t-connector coming off the left manifold to the brake servo and to the balancing pipe going to right manifold…. Do you mean you replicated this on your Dellorto setup? ˋNo need to connect to more than one though as double barrel carbs don't need the balance pipe which is the only reason VW did it that way killing two birds with one stone.´ This i don’t understand, sorry, it sounds like it contradicts the previous sentence, but I guess I am just misunderstanding. thanks
Also the heat insulators between manifold and carb, what is a good material for that, i found some fibreglass resin, and some bakelite sheets on ebay…. would those work? Is there something better? cheers
No, you got it - I did use the original solex carb balance pipe and connected it to one pot on each carb for the Dells because I thought it would look neat. BUT - there is no need to do this both in terms of double barrel carbs not needing a balance pipe like the solex do or the extra vacuum it gives for the servo. It did look tidy though. I say did because in the end while using a Morgan carbalancer I found the servo made the weights bob up and down so I disconnected one side and removed the steel pipe which allowed me to fit the servo non-return valve closer to the manifold which helped reduce the weight bobbing effect on the single barrel left connected. Hope that makes sense! Yes, I do enjoy messing about like this, it surely beat grinding and welding for entertainment. I had/have photos somewhere but can't find them.
That wasn't where I was going... reason I asked is that some nice things have been said above about Eurocarb and that may be true but the only reason i had those vents (and associated jets) was because when i got the carbs i was given different advice on setting them up so i asked Euro. those were the ones they advised. now anyone that says they have a standard 2 litre running on 34s ... far too big! so.. my point being is they either didnt know or just tell you what other people have ordered! That said it was a while ago that i was doing this. Incidentally... found a piece of paper in my jets box and apparently im running: 28 vents 127 Mains 57 idles and thats running rich with an after market mech fuel pump with no regulator! Next step is low pressure leccy pump that Ray donated (many thanks) and subsequently a regulator if still rich. after that im not sure where to go. (recheck float heights Im guessing then look at mains and idles)
