My brother is giving me all of his stereo equipment from his old car. He is also helping me with the installation (he just got married and does not use this car anymore). What a great guy! For the front he is giving me 2 4" speakers. I know this has been covered 100000's of times in all of the Z forums but I need help finding a good place to put the speakers in the front. I know that people have put them in the doors (last resort) and in the console on both sides and under the dash. I am most interested in the last two options. I have read alot about this being done but I am a visual learner. Does anybody have any pictures of their setup in the front? This is going to be done in a '73 240z. Thanks for taking the time to help me out.

Has anyone ever done business with alfa1750 on ebay? He has some pretty good prices on carb stuff. Just wondering. Thanks!

I think it would be cool to see just once to see what it would look like. Anybody want to photoshop it?

Thanks again for the info Chino. I think my jets are too big. I will try the techron to get rid of any carbon deposits. One more question. you said that I should "make sure that the throttle closes completely". In the steps in the link in my first post, it wants me to turn the Idle speed screw in 1 full turn after I come into contact with the lever(step 2). Doesn't this 1 full turn open the throttles a little bit? Also, 1 full turn means 360 degress right?(just a sanity check =))

I just bought this car in December and the webers came with installed on them. I know that these were running rich due to checking my sparkplugs and dark exhaust. I started having dieseling problems a few weeks ago when I tried to do some tuning without the synchrometer (I think I set my idle too high). I was not having backfiring problems before this. And my idle did not wander. I have been thinking that the dieseling could be caused by carbon buildup or advanced timing. I will check the timing this weekend. What can I do about the carbon hotspots? I was told by someone that it may go away after normal driving with a correctly tuned motor. A little history. When I bought the 240z I was getting around 12 MPG and have been trying to get it up to around 20 or so. Cleaning the carbs and airfilters brought me up to 15mpg and playing with the jets got me around 17mpg. so hopefully through the use of the synchrometer I can reach around 20mpg. So this has been a slow work in progress. Thanks for the info so far.

Yes, I am asking about Webers. Thanks for the advice guys. keep it coming!=) I read that advanced timing could be causing my dieseling. What do you think?

I got my Synchrometer and adapter for weber DGVs in the mail yesterday and went right out to tune. The instructions didnt make a whole lot of sense to me (inexperienced). Here are the steps I took and my results followed by my question. http://www.racetep.com/weberadj.html I followed the steps in the link above. After step 4.a I started the engine and it was running at 700 rpm. I connected the Synchrometer to the front carb through the adapter and check the primary venturi. It was at a couple lines above 10 kg/h. I then checked the rear carb and it was at a couple of lines below 10 kg/h (remember I already followed the first 3 steps in the link above). I then turned the idle speed screw on the front carb until it was a couple line below 10 kg/h like the rear carb. I then turned in the idle mixture screw to lean out the idle circuit. I got to about 1/2 a turn from an initial 2 turns out before I noticed a difference in rpm. I then connected the linkage and made sure they were the same length. I then put on the airfilters. Before getting in the car to go on a test run, I heard some backfiring from the exaust pipe (rich idle cricuit?). I got in the car and noticed the rpm to be at an acceptable 750 rpm. On the test drive I noticed on my first stop that the rpm went down to 450-500 rpm and went there at every stop. Everything else ran great except for some backfiring. When I got back to my garage I listened for a little bit and heard the backfiring and the rpm was back at 450-500. I then turned off the car and it started to deisel. I was tired and went to bed. I noticed the low rpm at stops and the backfiring again this morning on the way to work. It also deiseled again when I got to work this morning and shut her off. Questions: -Is around 10 kg/h good on the synchrometer? -In this case, what would cause the deiseling? (It was deiseling for a few weeks before I started the tune up. (could it be carbon buildup)). -In my case where the front carb is at a couple lines above 10 kg/h and the rear is at a couple of line below 10 kg/h do I tune the back one to the front or the front one to the back? Or do I have them meet in the middle. Do I changed the idle speed screw to change them and not touch the mixture screw? -Is my backfiring caused by rich idle circuit? -If my rpm is at 700-750 while tuning and at the end of tuning why would stopping during my test drive cause the idle to go down to 450-500 rpm? I know I have more questions but cannot think of them right now. Here are my Jets for reference: Pri Sec Idle: 60 50 Main: 130 120 Air correct: 165 160 Emulsion Tube: F-60 F-6 Acc pump: 50 50 Thanks for your help!

Will this choke knob work on a 73 240z? http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&item=7967794399&category=46102&sspagename=WDVW
