Passing emission test

Post by handymanpdx »

I have a carbureted vehicle we just added the MJLJ 4 to and are having trouble passing emission testing, simply leaning the carburetor isn't getting me close enough. Any ideas would help...

I did read a thread where user merlin said he increased the gap in his plugs to 1.05mm which should be about .042 in standard conversion, but he didn't say where his gap was before the change.

Hi - ignition timing can certainly affect your emissions. There's a lot of resources out there that might help:

Fortunately, Megajolt's ignition map lets you completely tune any region of your operating condition, for both operation and load.

let us know what you find out after performing some adjustments!
