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.

Cheers,

Sulio
