Upgrades
Just got done installing a Weber 32/36 carb on the 82 Corolla (3TC). Smog pump, gone. Header heat shield, gone. About 8 miles of vacuum lines and manifolds and solenoids, gone. Took about 8 hours so far...an hour to pull the old carb, two hours to scrape the damn original gasket away (seriously there was 30-year-old gasoline pooled in there), an hour to install the new one, about 30 minutes to route hoses correctly. Today, about three hours to pull all the vac crap off and try to set it up.
Before:
After:
It still needs a LOT of work, the idle set screw isn't even touching the arm (but the speed is good) and I need to keep tuning /everything/ but at least it'll shift. Everything I'/d read was whining about needing to fabricate a bracket for the kickdown cable after you did this and did that and cut the cable and put on the generic death-of-a-thousand-holes Weber linkage, so I just swapped the entire plate over. Yeah, it's offset a little bit despite the washers I shimmed it with. I had to adjust the throttle cable for maximum displacement away from the linkage and the kickdown cable for maximum displacement toward, but....work in progress. I can probably get a longer bolt if I'm willing to take the carb off and order parts, but right now I'm not. I figure I'll just make sure that entire area is coated in silicone so nothing binds and throw some zip-ties over the top of the cable notch so the cable won't slip out (it tries sometimes, but always pops back in again when I let off).
Linkage:
The sound when the secondaries open is pretty impressive. Unfortunately (because it's not tuned right for SHIT) the performance isn't quite there. Still, it'll chirp and driveline hop where it didn't before, so power is obviously up even in the current confused state. I also have the factory shorty headers (FINALLY got the heat shield off) so the next step will be just the catback exhaust to let me handle freeway traffic safely.
Second biggest project I've ever done. Given that the car still runs, and runs better, and that last time I swapped a carb I didn't get to do most of it and wound up pouring gasoline into a scraped-raw knuckle, I'd say the abrasion quotient is down and the satisfaction quotient is up. After Roommate gets back from her shift on Sunday afternoon I'll probably do the rest of the tuning. Until then, fuck this, I need a shower and a working/leisure position that doesn't try to deforest my lumbar region.
