NV Smog testing....FAIL

Julian,

retard the ignition (turn the distributor counter clockwise) until the motor will barely idle, re-adjust the throttle stop screw to bring the idle speed back up, now screw the idle jets in until each side drops the idle rpm by 100 rpm, then bring the idle speed back up again with the throttle stop screw. The engine should be idling much rougher than normal, but should pass smog. You have reduced the peak flame temperature & leaned out the carburetor.

After passing, you'll need to optimize everything again.

Now that I've told you my secret, we must become blood brothers or something.

George

George,

I'll make the adjustments tonight and get her back down the test station tomorrow. Will let you all know how I get on.

Thanks
Julian

Julian,
Your call but you have two options in NV. One open a PO box in Carson City or find a good friend in that area and register the car in that county. They do not have smog tests!

Second, after fiddling-farting around and if you are successful in passing. Get a historical license plate. As long as you keep the car reg current you only have to pass the smog test once and just show proof that it passed for years to come. Saves the hassle down the road.

Is it worth put on an oxigen sensor to measure o2? Or spending some time at/on a dyno with a carb tuner? Best power is generally at 12.7 but the cars need to be 14.7 to meet emisions.

Gary

Did they give you a print out of your results? Here is a good site with some good info on mixture vs emisions:

Also, if you need to add a cataletic converter to get it to pass (temporary), it would make a good write up.

Gary

Update: PASS

George's trick did the job, although I still needed the second chance option it did come in at 3.45% vs. limit of 3.5% on CO.

It overheated during the test (Fluidyne radiator and sucker fans have moved to #1 on the priority list of "to do's". I had to advance the ignition to get home again as it was so lumpy, but heck it's through for a year.

Thanks George for your wisdom. I'd happily become your blood brother if it means I get access to all that superior knowledge & information running through your veins

RoverLtd: The PO Box in Carson sounds like the solution for next year. I did look previously at requirements for a NV Classic vehicle plate and didn't like the fact it limits you to 2500 miles/yr. Thanks for the heads up, if you ever want to hook up some time contact me off DTBB at julian_kift@hotmail.com

I think you now have over 1700 registered blood brothers!

I love happy endings.

You mean I actually luck out on something because I'm in NY? No more smog testing on a car 25 model years old here. The black clouds from the Webers would be a definate sign of impending doom.

Julian,

I doubt there would be any wisdom or knowledge transferred. But you would probably get a buzz! lol..............
