I'm trying to sell a 73 Fastback I have. The buyer wanted me to get it e-checked, I was reluctant, but need this car gone. I brought it in this morning and it failed. Which surprised me cause it runs really good.
It is not FI anymore Dual baby Webbers (I-34) on a stock 1600 DP It had high HC at idle, 1223 and 1000 is the limit. Apparently HC are the result of unburned gas. At 2500 rpms it was within the limit, 734 out of 1000. Could this be something simple, syncing the carbs, adjusting the timing, I have nether the time, nor desire to F with this car. Could I just crank up the timing and run some of the e-check additives and maybe squeeze by. Or maybe lean out the carbs a bunch, and which screw would do that? Help I just want to wash my hands of this car. Samson |

Ben is right. The seller is legally obligated to provide a passed emissions certificate. It's not common practice, but if the buyer takes the car in to have the testing done and it fails he can come back on the seller. Samson, Run the car around for 20 minutes and get it good and warm. Well up to normal operating temp. Even a highway run at 65-75 for 5 minutes and then a drive around town. Then stop in a parking lot just before the emissions station and retard the timing just a couple of degrees. Keep the car running the entire time your waiting in line for testing. Should do the trick. You're not that far off. |

I've taken well over my share of 30 year old cars through Colorado emissions testing. What I posted here in addition to a snugging up of all manifold and carb nuts/studs/bolts will get the car through testing if it's only 200 PPM off on HC. If it doesn't, there's a bigger problem that eeds to be addressed. |
