   revs to 3000 and stops

   i have a 1972 240z and it's got a couple problems. it was running great a while ago, but i had the carbs adjusted and it wouldn't hold idle. i also couldn't rev it up or it would die. i adjusted the carbs again thinking maybe it was flooding the engine, so i made it leaner. it runs and drives now, but i can only rev it to 3000 before it sputters, backfires, and and stays at 3000. any suggestions as to why this might be and how i could go about fixing that? -Matt

   I've finished redoing my dashboard & since reinstalling it, my speedometers light is out...how can I go about checking this? It worked before...Is there an easy way to access the bulb without removing the dashboard? (because that just isnt happening) --- There is a screw securing the gauges to the dash, on the inside top; does this remove the gauges from the dash housing? Help! :surprised

   Rough Running

   I have a 1971 daily driver and it is reasonably stock with unknown miles. I run: Mallory Dual Point mechanical dist MSA Header NGK Plugs and wires MSD Coil It runs strong but I am having a problem suddenly and am stumped. It “rumbles� when the car runs and seems to lack power a bit. Normally acceleration is nice and smooth but it idles rough and “growls� when I get on the gas. Almost like its missing but not quite. I have replaced plugs, timed it, adjusted/synched carbs (SU’s), replaced wires and swapped coil. Each thing helped a little but the problem persists.

   No Power

   I've been restoring an early 74 260Z, and I have it almost complete. There is a show tomorrow, and I don't know if I can go now! I removed the dash to get it recovered, and when reinstalled, I now have no power. I also went ahead and bolted the battery down (requirement for show-and-go). I have power at the starter, and I have a good ground through out the frame of the car. I have no power at anything else, not even the under-hood light. What I am wondering is: a) Is there a ground for the electrical harness that I accidently disconnected? Where? Did I break a wire somewhere? c) other? Any help you can give me today will be a godsend! Thank you!

   i acquired this car after the p.o. gave up on a wiring migraine. (search in electrical to see the ridiculousness) the owner before him had it running but went to work one day and came out to be unable to start it. i have fixed the wiring and i am getting fuel and spark. i can smell the fuel and know the distributor is firing when attempting to start it. the only thing is that the car has been sitting for about a year. it had a little under a half tank of gas when it was parked. i just put 5 gallons of premium in it w/ some fuel injector cleaner. it turns over but just won't start after about 30 minutes of trying. i don't know what the problem could be. it is …

   Wheel size (a '81 wheel to a '71 car)

   I have set of steel wheels (TOPY 8-80 5 1/2 JJ X14) that came on the '81 280ZX that I purchased new. I've searched, but I can't determine if this wheels will fit a 1971 car. I believe the wheel will fit under the wheel well (?), but I have no idea if the offset will be different? I assume the luge spacing is the same? Thanks.

   Blew a head gasket, rebuild engine advise please

   Hi Guys, It appears I blew a head gasket. After my engine warms up it starts smoking (white smoke) I've had to refill my coolant a couple of times in the past couple of days. Anyway, since I now have to take the engine apart I was wondering if while I'm replacing the head gasket it's worth replacing the rings, crank bearings, etc (minus the main bearing since it would require more disassembly) and do a partial rebuild for lack of a better word. I would like to do an engine swap in a couple of years and just looking to do give new life to this tired engine. Any suggestions and opinions would be welcome. Thanks, Rick 1978 280Z 2+2 stock engine

    Honda wiper motor failure

    I did the Honda wiper motor swap as described by Zs-ondabrain. http://www.classiczcars.com/forums/showthread.php?t=28989&page=2 I tested it, buttoned everything up, re-tested and called it a day. Fast foreword a month, it finally rains out here in Tucson, I hit wiper switch and.... nothing. Fuse is good and all the connections look tight. Using my 12 volt tester I find there is power at the fuse box, and at the 20/30 amp 12 volt relay. Advice? Suggestions? Thanks!

    Vegas or Bust

    Anyone know a good trustable shop that would do a restoration for me? Perferably in the Las Vegas area. Also, My car has been a shop for a few months now, and the problem still hasn't been fixed. It is choking out. The Mass Air Flow meter was replaced, and I've replaced air filters, fuel filters, most questionable hoses, PVC valve, Distributor, and more that I can't remember at the time. I'm thinking that the CPU might be bad, but would it at least run? Its a '77 280z. The fuel injectors were all replaced a while back so I don't think its them either. I'm running out of ideas and things to replace! Could low oil preasure cause this?

    WHat is the base timing on a stock 240Z

    I have checked my timing and at 700 to 800 rpm, I am sitting at about 7 Degrees of advance. Is this right? Also, just a note, at 2800 rpm, I am at 44 degrees. How does this stack up to what it should be?
