what would you recommend for a warm 240 with a lumpy cam and shaved head?
I'm pretty sure i have drilled the jets out to mains of 150 and idles of 50, but i just cant get the revs to climb up to 2500 rpm.

This program is for 4 cyl engines so you need to recalculate engine size in cc's using.
Size in cc's divided 6 then times that by 4
So for a 2.8L it would be.
2800 divided by 6 = 467 times 4 = 1867cc

I am not pretending to be a carby guru, and there is so many conflicting ideas and preconceptions about what is good and how to set them up, that i'm not prepared to offer particular jetting combinations for cars. What works on my 260z may not work on another. ther are too many variables. RE: Head work, Compression ratio, camshaft, exhaust system, etc. These were starting points only. I do however suggest getting the Weber and Dellorto book that I mentioned and read it at least twice. Be cautious when buying secondhand and get them tuned by someone that knows what he is doing. These are great carbs. When you hear about people denigrating them they have probably had bad experiences trying to tune them themselves. ( If it doesn't work right it must be the carb. No way could it be the operator ). By the way NEVER drill a carby jet. Why do you think they cost so much. These are precision parts designed to do a precise job. I'm not having a go at anyone in particular, I just don't like seeing people wasting good money on someone elses problems. Expect to spend a few Dollars getting your carbs sorted out, but in the long run you will love it. Regards David.
