Now I am completely confused. Based on what this guy has stated, my 15-17 mileage in city driving isn't absurdly low?

thanks! i was using the 5/8.

That's a good baseline to start from to get a feel for it. I don't really believe most of the rules pertaining to the number of turns, though. If you're more than their 'limits,' I wouldn't be too worried. I also don't see it mentioning checking the spark plugs. I'd try to do close to what they say, then look at your spark plugs and see how close you are to being right. If it's a nice brown/tan, you're near perfect. If it's too black, it's too rich of a mixture. If it's too white, then it's too lean. Don't be afraid of trying it out. Sure, you can delve deeper into more complex tuning with different jets and such, but just getting the idle smooth and the spark plug to look a nice brown/tan is close enough for me most of the time. If it stalls out under high fuel demand, or floods itself, then you need to adjust the float. i found the smoothest idle by using the mixture screw only with the idle speed screw back completely off the throttle. i then turned the idle speed screw just a hair into the throttle and that was it. i'm idling around 700. are the plugs smaller than standard? i tried removing them with a standard socket and couldn't grip anything. Weird. And i've changed many plugs on different cars. A 13/16" spark plug socket should work fine. My standard Craftsman toolkit comes with two spark plug sockets, a 13/16" and a 5/8", and those have worked for everything for me, from mopeds to lawnmowers to motorcycles to cars. Maybe somebody put some weird plugs in your engine, or you're not diggin into them right. I had been trying the 5/8". Thanks, will try the 13/16.

I have a '74 2002. Tried using the standard 5/8 socket to remove my plugs and no luck. Is that the correct size or is it: 13/16 in. Socket 18 mm. Socket 3/4 in. Socket 9/16 in. Socket

the way i read it was smoothest idle as possible with just mixture then bump it up to 700-900 with idle screw? the cars runs fine imo i'm just having issues with really bad gas mileage

http://www.carburetion.com/weber/adjust.htm I found this site which makes it look really easy. Some I have spoken to have said that it is really complex and that i need special tools for readings. And if I do it wrong I can really screw up my car. Have anyone adjusted their own Webers? Is this article above correct. I've located a few with the same information.

Wow, thanks for the heads up.

40-50 around LA, nothing too spectacular. rarely in stop and go traffic either.

i'm getting 15-17 local traffic in LA. I took a look at the air filter and it didn't look too bad. I then backed off the idle speed screw and adjusted the idle mixture screw. I think the idle screw was opening the throttle a hair too much and maybe the carbs were a little rich. Performance-wise the car seems to ride a bit smoother with a little more power. Not that I thought it was so was bad before but I feel an improvement. After this tank of gas if I don't see an improvement I'll take it to a shop to get the weber calibrated. Has anyone in LA used top-end performance in north hollywood for repairs?

1974 2002 with rebuilt engine with only 3,500 on the clock, a weber, new tires. car runs and sounds great. i'm getting between 15-17 mpg. what gives? i'm thinking about cleaning the air filter (are k&n just as good as weber filter), and replacing the plugs. Could a dirty filter kill that much mileage alone? I'm confused cus the car runs great.

did u do the install yourself? easy job?

Can anyone recommend a short shifter for a 4 speed 2002? Thanks.

if my calculations are correct i'm only getting around 17mpg.

Hey guys what is the fuel tank size on a 1974 2002? I'm not sure my fuel gauge is accurate. Also wondering what sort of gas mileage to expect. Thanks.

I've had the car for a little over a month and it has just over 3K on a rebuilt engine. The noise doesn't bother me as I prefer to hear the roar of an engine and rarely played the radio in the 3 porsche's i've owned. Based on all the replies I guess these engines were built to be driven @ higher rpm's; so I'll just keep the car as is for now. Thanks for all the replies. I just got a quote from the guy who rebuilt the engine for $1200-$1500 to locate and install a 320i 5 spd trans in the car. Extremely reasonable. I'll decide later this year. I suppose I should enjoy the car in stock form for for at least a little while. Jack Fahuna also told me he prefers the cars be left as 4 speeds and said they were meant to be driven hard; not just to be used as beach cruisers!

I got a quote of $2500-$2800 from La Jolla Independent. What's a good price? Any recommendations from people that had it done in CA?

Any thoughts? Any time i'm driving at and above 65 mph the rpms get really high and the engine is quite loud. As i'm used to more modern vehicles with 5-6 speed transmissions and larger engines, it sounds like i'm going to damage my 2002. Also the speed limits were much lower in 1974. How hard can you drive these cars? And how fast is too fast for the engine? Most people in California just cruise around the beach and tool around town in these cars. I'm all for opening mine up on the freeways.

I tried that but now the problem is worse. I had to use so wire now to keep the trunk closed. The hook latch is basically worn. Going to get the part tomorrow and replace the latch assembly. $40 from dealer. I guess after years of use, it's a 74, these things get worn out.

Anyone experience this? Wondering if I need a new lock? If so, where to buy? Thanks.

Hey guys, wondering what your feelings were about putting a 320i 5 speed transmission into an 02. I know a lot of people do it, but do you believe as a result of lower rpm's being run with the added gear that it will increase engine life?

thanks mike. i just need to re-adjust the height. make it a little lower as the top scrapes now. any ideas how i do that? thanks. Easy as pie. Adjusted roof from below after removing headliner panel covering sunroof. Turned the screws and nuts. Bingo. Thanks everyone

Did you remove the headliner at all? My sunroof works great except the top gets scratched when opening and closing.
