If you have to do an emissions test, do what ever you have to do to make it pass and then change it back afterwards. How often do you have to do it?

Run the gas down til you get the idiot light. Add 1 Qt denatured alchol run it through then fill the tank after to dilute. It burns with out producing CO, and is used on board boats because of that. However it is not good for certian kinds of plastics, so you will not want it in your tank for very long. (IMG:style_emoticons/default/happy11.gif)

thanks

I've gotten a few carb'd cars (still have a one of my old Chevy trucks laying around in addition to 914's) through testing that were on the edge of CO by retarding the timing a tad.

Just a little, don't go crazy. You're not far off anyway. Changing the timing may very well affect your HC a little bit too. If it costs you to have the thing tested every time it might be worth it to pay a shop this time for 30 minutes labor to put it on an analyzer and adjust it to pass. Or find someone that has an analyzer. Then you can tune for performance after the test and make notes on what timing and mixture settings it took to get it to pass so 2 years down the road you can tweak,test, re-tune and be done.

Jim,
If you were to lean out the idle system a bit, team that with a 4 to 6 degree retarding of the timing. Doing that together may keep your HC from spiking. I assume you are doing an idle and cruse test? For the cruse portion I would install a new air-filter, make sure the choke plate is open all the way and you may be good to go. Your not far off, those readings and limits are insanely high compared to new cars. My guess is you take the place of around 300 new cars just with you V8 car, Ha Ha Ha isn't that great!

Jim,
I have a new GM crate motor much like that in my V8 car and it really runs great! I have no emission testing here in Ca. but surely it would help to have a fresh set of valves. Your carb and ignition systems would likely still cause the engine to fail, you just need an adjustment or two. (IMG:style_emoticons/default/driving.gif)

Crap! Sorry to hear that. Can't you just get Antique tags and bypass the whole emission scam deal? If all else fails, sell the car to me (IMG:style_emoticons/default/biggrin.gif)

Running any emissions control on the exhaust side?

Also heard of running a quart of acetone to help with bringing down levels... Never tried, we tune our cars to pass if asked and paid to.
