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.)

I only have one thing to say.....



Carburetors = 70 year old perfume atomizer technology.

Weber Carburetors = Italian chokeless version of 70 year old perfume atomizer technology. (It doesn't get cold in Italy)


Electronic fuel injection = High tech, modern, computer controlled technology.



Put on Fuel Injection and be able to lean in the window and start the car cold in 20 degree weather. (IMG:style_emoticons/default/poke.gif)


(Above does not apply to Mechanical Fuel Injection, it is friggin worse than carbs for cold start!)

First off...clean them
Have patience when you start the car, and the 70 year old technology will still work fine.

and Clay...Show me a system, a total system, dollar for dollar the same that will produce the same results, I would be happy to do it.
When IC systems that cost 1-2k...and what, 100 hours to install and tune..hell give me carbs for a few more years...

BTW, I run stock FI on two motors..and I love it...starts fine.

But...when you want to change the cam,,,you are forced to buy either carbs or some outrageous home brewed system that could work, could suck...might need to spend 100 hours on some web site to learn how to spend 100 hours tuning it..

I can still go buy carbs, and bolt them on,,,without thinking...and enjoy the drive.
