Motorsport Mickey Posted July 5, 2020 Report Share Posted July 5, 2020 Hi Hamish, Are they a matched pair ? can you blow up the photo to compare the stampings ? even then you'd have to compare the progression drillings to e sure. Mick Richards Quote Link to post Share on other sites
Hamish Posted July 5, 2020 Author Report Share Posted July 5, 2020 Very close numbers mick the missing chokes was too much of a gamble for me At those prices and I didn’t know what size the existing ones were I think I’d need 34’s they were also selling a spare lid for a 42 Quote Link to post Share on other sites

You don’t want to know that There’s a pair of 34 mm chokes for DCOE’s on eBay at the moment. In any event, surely if you have one, you should be able to find someone who can manufacture a matching one. Rgds Ian Quote Link to post Share on other sites
Hamish Posted July 6, 2020 Author Report Share Posted July 6, 2020 Hi Ian i have seen a package of used chokes on eBay but the 42’s are ID for the DCOE 48. i don’t know what the chokes were on the “complete” carb. But I know anything can be made. I know the chokes for the dcoe40’s are the same design for the 42’s but the wrong size ie 2mm too small and the 45’s are a different design so can’t be machined/turned down is this correct ? so you have to search for 42dcoe then also search for the correct chokes ????? would someone in the know clarify this for me please. im not really too sore about this it’s what eBay or is all about. But I can still live in dream land hope that a set will come up that others don’t notice that I can then afford. I have contacted an acquaintance with a set from a Morgan but he is happy to leave them on the shelf in the garage whilst he has 45’s on the car. Quote Link to post Share on other sites
Ian Vincent Posted July 6, 2020 Report Share Posted July 6, 2020 Hi Hamish, If you haven't aready got one, you may find that a 'Sniping' app makes buying things on eBay a bit easier. Rgds Ian Quote Link to post Share on other sites

Rgds Ian I’ll have to have a look. But to be honest given what was missing and broken and seized With those carbs the bidding went beyond what I was comfortable with.

MilesA Posted July 6, 2020 Report Share Posted July 6, 2020 In terms of spares, I have used these people a couple of times, but unless I am missing something they don't seem to have any thing for 42DCOE https://www.webcon.co.uk/default.asp Miles Quote Link to post Share on other sites

I think you are right Stuart but for me a risk too far being on my first steps of learning these carbs I'm right in thinking that the dhla40’s shouldn’t have a suffix letter for my 87mm bore car That is used in sprints ?

Depends on the suffix and they can be modified to suit as its usually removable parts that make the difference or they can be redrilled to suit. Stuart. Quote Link to post Share on other sites
Motorsport Mickey Posted July 6, 2020 Report Share Posted July 6, 2020 If it's performance at a cheap price the Dellorto DHLA 40s are the model to go for, spares are available easily across their range. Mick Richards Quote Link to post Share on other sites

Mick Richards But Mick it seems some are cheap because they are “emissions compliant” or turbo versions depending on the suffix. so one needs to be careful as to the type it seems.

H I have the emissions version on mine and I can assure you that doesnt make any difference to the way it goes! All that means is a couple of adjustments have seals on them, easily removed. Stuart.

For me Hamish you are a brave man buying second hand of any type, I would go new 40s then over to Dennis Vessey to set up right he will not only do machine work and modify jets or change to suit.

Steve Priest Posted July 6, 2020 Report Share Posted July 6, 2020 For the non-experts among us (and I include myself in that), I found this quite interesting as a bit of background reading: http://www.tr3a.info/WeberDCOEinfo.htm Steve Quote Link to post Share on other sites
