Any advice/tips (apart from replacing it with a standard one)
ill strip/clean and put it back together with new gasket etc,
Ive Noticed it floods & leaks a bit from the Accelerator pump.
im going to check the diaphragm, try a 1.22 & 1.25 Main jet instead of the current 1.30
as it runs so rich im constantly getting black soot out the Exhaust..
Any advice tips wil be highly appreciated peeps
Feel free to pop round for a cuppa and help
Check the rest of the jets for there sizes, once you cleaned it all thoroughly and put it on car check the AFR's and adjust jet sizes to suit boost your running

My AFR is in the post,
Wallace is going to solder it in to the downpipe for me.
I have several new Jets 1.22 1.25 1.30 etc..
Think maybe the 1.30 is too big.
Is it true that they can soldered down in size?

Yes you can solder the jet and then re-drill to what size you are after
Is this the dreaded Diaphragm? (see att pic)
I noticed 2 or 3 very small cracks/splits so did a macro shot highlighted in yellow.
Another question is, would this be the cause of slight fuel Seepage in the other pic,
where the Acc arm moves back n forth?
Because even stationary engine off its slowly seeping out.
If it is, i don't have a replacement and wondered where i could buy a new one.
Thanks
Stu
yes that gasket would be the cause of the leak, not sure you can get the gasket individually think it's in a complete gasket set only. Worth messaging Mike he will confirm if available seperatly.
Excellent! Thanks.
I'm hoping that's the only cause!
Ill ask around if anyone or Mike has a spare to sell,
if not buy the set
For the cost of a gasket set worth replacing all the gaskets with new and giving the carb a good clean throughExcellent! Thanks.

Yea I was given a bag with the car with Most of them as new, but no Diaphragm or the main Rubber gasket (big one).For the cost of a gasket set worth replacing all the gaskets with new and giving the carb a good clean through
yes that diaphram will be the cause just had to do mine after same problem
Need a Diaphragm so will have to just order the whole set.
Id like to get the top plenum O ring seal aswell.
Wheres the best/cheapest place?
Our very own club shop: https://www.rtoc.org/shop/index.php?m...sl238v8qivusb2
Tried to look for a basket or purchase item then noticed the "Sold Out" sign
Just Emailed Mike, need to order the whole kit just for a Diaphragm
0 Units in Stock
Just see them on on Ebay for £28
Yea thats the one.. Whoever contacts me first gets the deal LOL
Extra £ for the throttle seals, and that kit doesn't come with the idle jet o-ring, nor the large plenum o-ring.
If the club's out of stock though, I guess that leaves little choice...
Saying that, if you can hang fire 24hr, I'll have a look in my box of carb' spares to see if I've got a spare accelerator pump diaphragm you can have.
Thanks Mart,
I see you like Pie n Mash, you from east London?

If club is out of stock, I did speak to Ian telling him what I can get them for the club.
Ordered kit & Plenum O ring off Mike this morning, done a good deal.
Need to get this carb back in for the weekend..
I did see a Diaphragm for £20 on its own but i aint a mug lol
Measured my main jet, its 1.3
I have another jet that is bigger than a 1.2 (1.2 drill bit moves around), but the hole doesn't fit a 1.3 drill bit, on the side the marking looks like a 1.25.
Also, Could someone show me where/what the Venturi is/looks like?
I have a standard T2 (i think), Group A carb (apparently the venturi was enlarged) and a 1.3 installed but the carb overfuels like crazy and sends out **** loads of soot on the exhaust & plugs..
Should i use/try the 1.25ish jet? or just go with 1.2?

As said on facebook ditch the large venturi carb and get a std oneMeasured my main jet, its 1.3

This is a std venturi carb

Agree with jtec, get rid of the group a body and fit a standard venturi carb
Is this Group A worth more or less than a standard one?
I'll replace the few bits that need replacing, put it back together so its in good working order then flog it on Fleabay and buy a std one.
