on my 74 260z i got for free the owner before last adapted what looks like a gm coil to use on the z, it looks as tho he just wrapped some wires about the orignal eyelet connectors and put tape over it, could this cause, resistance? thus reducing spark? the plugs have been black and it smells of gas when i have the choke on, but according to what ive read and been told my carbs have been adjusted properly (stumbles but keeps running) im going to look under the tape tommrow and see whats up but could that be a problem?

ok looked under the tape that was there on the yellow black wire and he soldered it to a wire that goes to a spade connector that hooks in the coil, looks like its not a very good solder joint anyway also there is a wire that gose to what looks like a condescer thats next to the coil dont know it thats is suppost to be there or not.. help is welcomed

That condenser is a capacitor used for supression of noise that can bleed over into your radio/stereo. Most cars have/had them there and they do not hurt anything.

I would suggest using an ohm-meter to check the condition of the main coil wire and spark plug wires and checking visually to see if the rotor and distributor cap are in good condition. Even i they look OK, if they have been there for a long time, I would replace them anyway as they are not expensive. I'm assuming that you have new (or reasonably new) properly gapped spark plugs already installed.

If the engine/carbs smell of gas with the choke on it could be that even with the adjustments done to the best they can be done , the carbs are not reacting properly to those adjustments. Are these real SU's or BOAT ANCHORS?

they are 3 screw round tops, i replace the coil with the correct one and got rid of that Capacitor as my repair manual wiring diagran dont show it there it was also soldered in the eyelet connector, it seems to run a little better now got to replace the plug wires soon they are pretty ratty, the spark plug are fairly new i put them in when i got the car they are the cheap autolights but that was the best i could afford at the time and they do ok.
