atypical topic for idf

[monsters]

Good morning everyone, you may never come across this accessory that is used to power a Weber IDF engine with LPG or cng. It was mounted on Alfa Romeos since the early 80s. The problem in mounting it is ensuring the venting of the idle jets for petrol operation.
To solve the problem, I inserted some jec doctors to the plate. My carburetors are idf 82/83. Now the engine works perfectly both on petrol and cng.

using a valve I reduce the air flow to make it work correctly on CNG. all electrically

I don't understand what the problem was, as the path to the idle air bleeds is not blocked by this plate, but I am glad to hear this modification solved the problem.
And thanks for sharing, that's is a very nice setup!

Not near enough information to understand what is going on here...
