Tough cold-starts w/chokeless Webers..., any secrets from you northerners? Options

[PinetreePorsche]

My 2.0 w/ Webers will fire, catch for an instant,and die. Each re-start, the instant stretches out, till, on the 4th try, it runs for maybe one second, and the 6th or 7th it goes for 2-3 sec, and maybe the 10th or 12th, it will stay running with lots of artful foot flutter on the gas. Less artful and it dies--until it has had about 15-20 sec of uninterrupted running with the foot flutter. Even then it needs just a slightly high rev, like 1800 (hate to do that when it's still cold), then, after another half min, I can let the foot off the pedal and it'll stay running. Then, maybe another 15 sec, I can lift my clutch foot and not have the extra load of the heavy oil kill it again (maybe keeping the revs at 1000 with my foot). Finally, after 2 min total I can get underway, if I over-rev it pulling away in 1st. Still, it will back-fart a bit if I gas it too much after a shift to too low a rev. By 5 min, as the heat starts to come out on the glass, it gets more normal. SO: you far northerners with carbs --what can I do with choke-less Webers to make this a kinder, gentler process? (Yes, if there's salt on the roads --last 3 weeks here-- I leave it at home. But the warm and rain are coming for 2-3 days, so it will get out again, and I'd love to do right by it.)
