Compression Test
I did a compression test yesterday on my 240z and it was this: #1 - 180 #2 - 177 #3 - 180 #4 - 183 #5 - 180 #6 - 184 The #3 cylinder compression came up slowly (over 10 revolutions) compared to the other 5 cylinders. When the car is running I can pull the boot off the plug of cylinder #3 and there is no rpm change as there is with with the other 5 cylinders. The engine does not run smooth but it is not irratic either; the engine also runs well under acceleration. I am also getting a spark from the boot to the plug on cylinder #3. Do I need to check the timing? I don't understand why the compression is good across the board but it seems like the plug in cylinder #3 isn't firing. Please list any suggestions you have. Also the front 3 plugs (1,2, and 3) are almost fouled out from the front carb running rich.

Blinker works, well sometimes...
First off I have searched and read as many posts as I can about cleaning the connectors on the turn signal switch but no answers to which I'm looking for. My right blinker works fine (lights up on dash/front signal light/back signal light) but my left blinker only works on the rear signal light. When the blinker is in the left position I can hear the flasher working but the light on the dash and the front signal light does not work (doesn't even come on solid). When I flip the hazard switch all of the lights work (and flash) on the dash, front signals, and back signals. Anybody have any clue?

Rich SU Carb <- Newbie
Hello, I bought a '72 240 a couple of weeks ago (I also have a '90 300zx) and I've been reading up on everything I can get my hands on. Anyways I noticed the other night that it stumbles a bit on acceleration under 2k rpm's (but not through the rest of the power band) and I could tell it was running very rich. I pulled the plugs today and saw that cyl. 1-2-3 plugs were very fouled with carbon while cyl. 4-5-6 plugs looked very clean. I've read a lot of threads about tuning the SU carbs and I was wondering if I needed to completely tune both carbs or can I just adjust the front carb to keep it from running too rich. Any help is appreciated.
