toecutter Posted March 30, 2008 Share Posted March 30, 2008 Hi Guys, I've installed my tripple DHLA40L Carbs recently. The motor is an L28 and in need of a rebuild in the near future, perhaps 6 to 12 months away at this point so I don't want to blow a heap of money getting them professionally set up on a dyno until after the rebuild. In the mean time I thought I would get them running as well as I could. My L28 is stock with elec dizzy, headers and 2 1/4" pipe with a hot dog and turbo flow muffler. The engine idles ok atm however running extremely rich. I've been using the Des Hammill book "How to tune Webers & Dellortos". Anyhow I've attached a spread sheet I hope to build on as I fumble my way through the world of tripple carbs. Please advise me of your tripple set up and have a look at my info todate correcting anything that might sound off. I know there are alot of variables depending on engine set up and driving style when it comes to tuning tripples but I'm just trying to get to a start point and then keep fine tuning. I hope to keep some mid range power rather than have a car that has to be driven around at 5500rpm every time I go down the street.

Gareth Posted March 31, 2008 Share Posted March 31, 2008 Hey Sulio, looks like you're using the Des Hammil book too... I haven't installed my carbs yet, so I can't give you any advice, but why don't you post this info on classiczcars.com? I think that most users here use triple Weber DCOE and Mikuni-Solex PHH instead of Dellorto DHLA, so it may be worth trying elswhere. I'm in an even worse situation, because I bought two sets of Solex C.40 ADDHE carbs, which almost noone knows how to tune (apart from BMW Alpina guys - some Alpina 02-series cars had these fitted). Maybe you should get yourself an Innovate LM-1 with a wideband and narrowband Lambda meter? Tony Quote Link to comment Share on other sites More sharing options...

toecutter Posted April 1, 2008 Author Share Posted April 1, 2008 Hi Guys, Thanks Gareth, yep also posted on ClassicZ.

toecutter Posted May 24, 2008 Author Share Posted May 24, 2008 Maybe you should get yourself an Innovate LM-1 with a wideband and narrowband Lambda meter? Yer, I was just going to install an LSM11 Bosch Lamda sensor and use a local kit I can buy for $60.00 that provides LED display for AFR. I updated my spreadsheet just in case anyone was interetsed.
