After finding a completely rebuild Aisan carb in Craigslist, I mailed the advertiser who was in Napa, he called back on Monday, and I picked it up the same day. Installed it, and my problems were gone. New plugs, cables, distributor cap and rotor, timing checked, and no more gross polluting. Unfortunately, I forgot about the leaking fuel filler hose, so still have to repair that before I pass smog. I think my old carb was rebuilt by an amateur, who forgot a couple of ball valves. The rebuild kit has all of those, but I'm not going to put time in it anymore. If anyone wants to buy my old carb and rebuild it, it's for sale now, incl. the kit for $150. Pics on reply.
