Very nice find! Especially about timing and pump jet tuning.

What a great reference / article! IMO anyone who is running IDA's should read this. I have other references for IDA's but this one has real world tuning advice that is really helpful. Also the section on fuel supply and regulators is excellent and has great information. I'm about to go to an electric fuel pump and regulator setup and instead of just using what others have used I'm going to use the information in this article to make an educated choice. I have read this information by other knowledgeable resources and his advice agrees with what I've read.

Thanks for posting this Ron!

Found it while surfing for some info on a 46 Ida I won on eBay

Haven't had time to read it all but really interesting

The article you posted also has good information about cams and cam selection for an IDA equipped engine as well. Also, if you search the old Inglese induction website information he / they used to have some good technical and general advice regarding Weber tuning. Inglese was purchased by another company now so the current website is different I think.

My curiosity get the best of me......THE website is jiminglese.com....Jim Ingelse has been working with weber carburetors for 35 years and is still doing it albeit for the V8 guys...nonetheless, a lot of great information at his site....under common questions - a great little section on cam selection and lobe separation angle. This is also discussed on the site Ron posted....I think Ron visited Jim Ingese's website as the tools and graphics are the same....I was surprised to learn he's from Connecticut, same as me  (I live in Florida now though)

Great!Thank`s for posting that link.

Makes so much more light in some dark spots about the IDA`s espacilly with the pump jet exhaust and idle holder.
How much gears (3,4?) does a cobra have? As he writes about tuning sugesstion with second and thrird gear selection.
That info with the extremly helpfull knowledge of Jim Ratto about the different emulsion tubes, some time, and bang your done 

For complement the Ingelese link written above:
