After using last year's Nevada emission's test report to realize my car was running a bit lean I took some steps to enrichen the mixture (i.e. main jets. idle jets). I have a 32/36 DGEV and now I'm not sure if it is too rich (it does run alot better) to pass the test this coming year. I was wondering if when test time rolls around if I just put in a lower numbered primary idle jet (a 55 to say a 50 or 45) might that be a sufficient hedge to lean the mixture out a fair amount......hopefully enough to pass an idle test and a <2000 rpm test??? .

Any suggestions appreciated.

do you still have the old bits you changed to make it richer?
if so you could put them back for the test then change them back after

I have them......but I was trying to do as little fiddling as possible to get through the test.

The idle jet will work from idle to about 1200-1500 rpms. If part of your test is above this rpm, then you'll have to change the main jet too.

Thanks Bob. That's what I was wondering.
