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.

Seems like leaning it out a bit would work to pass emissions. Set it back when you are done. You have to get a 73 emission tested?

make sure you have NO intake leaks. retarding the timing can help bring down the h.c.'s. vw's run "excessive h.c.'s" when running good unfortunately. and unfortunately if you keep it running as when it passed the smog test you'll probably burn it up. some times you can just lean down the idle screw mix and bring down the h.c., but usually it will lightly missfire bringing the h.c. back up. it really is almost impossible to do by ear with out a c.o./h.c. machine.

anyone ever mess with achol mix for smogging?
