Well I will almost certainly not bother with a bodged (home made) adaptor plate. If I can buy something that does the job properly then fine.
Otherwise, I may try and weld shut the manifold stud holes and re-drill the studs to suit.
If that doesn't work then my new 30 DIC will be listed back on ebay...
Home made doesn't have to mean bodged. It will be as good or bad as you make it. My adapter for the torana was made on a home made cnc machine, it looks & is finished as good as a professional adapter for nowhere near the price!

No offence to other DIYers... I was just basing that on my DIY equiptment/abilities. I have become rather intolerant to things which dont work/look 100% (eg wheels rubbing on some setups)
Some jobs interest me and I dont mind investing time into those, but for a job like this I couldn't imagine fabricating something up myself in a reasonable amount of time (and time is money). So if it is too much hassle, then I'll just sell it and buy something more appropriate which will work...
Thanks for that Brayden.
The spacer that you made looks fine, but there is no way that I could manufacture something like that with the equiptment I have. ;-(
As for the adaptor, it looks like the dvg (?) webers have a bigger stud pattern than the mightyboy manifold. I need to reduce from 80x43 (MB) to 73x42 (30dic).
I have found someone on ebay who claims they can do an adaptor to suit what I want to do, so I'll wait with cautious optimism.
I'm sure you're all sick of talking about Webers, but I just got one with the intention of sticking it on my F8B.. However it's a 30 DGS - apparently off a 70's Citroen G / GS.
According to http://www.fiatparts.com/carbs.htm it's a replacement for the 30 DIC - and from the measurements i've taken (stud pattern 73x42) that seems to be the case.
What I was wondering was if anyone has found an off-the-shelf adaptor for these measurements (fritz?) as the redline distributers over here reckon the smallest they go is 95x43 (redline part 10-112) which I assume is for the DGV series.
May look at getting one made up custom by the local weber specialist, as I don't really have the equipment to make one myself.
Neh, not at all sick of talking about it yet. One day WE WILL find a decent way of carburating a mightyboy.
Only problem with discussions about this issue is that very few people have actually gone down this road, and opinion isn't fact.
I'm still very slowly pondering of ways to get my carb working on my car. As stated before, I'm not prepared to do a bodge job.
I'm still also on the lookout for another type of carb which may be a direct replacement. There really must be some available...
And Brayden, the pictures in your last post show the adapter you got from redline, that must be the 10-112 one that adapts the 80x43 stud pattern of the manifold to the 95x43 (?) of the DGV series. Is that right?
I think its looking like the only way to adapt a 30DIC (or a 30DGS in my case) is to make a custom plate.
The problem for me is that the bolt patterns aren't different enough to allow an offseting by use of a adaptor plate. The dvg carbs are substantally bigger than the MB pattern, so it's a lot easier...
My current line of thought is possibly welding a blank plate to the manifold (assuming aluminium plate will weld to it???) and then re-tapping to the desired pattern.
Could end up looking messy, but if done properly maybe a sand blast would clean it up nicely???
I ended up giving it to my uncle who is an engineer and he just drilled out the holes a bit to suit stud pattern so it would bolt straight on with no adapter plate.
My old manifold and carb is up the coast so I won't be able to put any pics up for a bit, although I may have some floating around from when we installed it. Will have a look and see how I go.

I take it you mean the base of the carby, it's stud holes were drilled a bit to make it bolt on? If it's done neatly nobody would be able to see, which would be very nice indeed.
How much better do the mb's run with Weber's fit to them? More powerful? Better or worse mileage?

Yep, the base of the carby. Used some allen key bolts to hold it on and presto! It went heaps better with it on, even though it was constantly giving me hassels. Mileage could be bad if you drove it heavy around the city (coz of mechnically operated secondary) but if just being light it would be pretty good, about the same as old carb.
The only real messy bit was hooking up the linkages as they were on the other side of the carb...

I have no idea why nobody has tried the stock carby off a non-turbo Charade! They bolt straight on, and being tuned for an engine with 200cc more size they would have to be close to spot on for fuel delivery for a "warmed" F8B.
