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.

cool - so i was not wrongly advised - will try that - that - jim 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. |

nope - no charge to have it retested.
