Well, you re-wired it so I need to guess a little. It looks like the green wire is the one that leads to the distributor, that should be on the coil negative side (terminal 1). No other wires attach here, the others all go to coil positive side (terminal 15); that includes the wire that comes from the side harness (ignition switch), the wires that go to electromagnetic pilot jet and choke heater on the carb, and the wire with the in-line fuse that goes to the back-up light switch. So get the red-double wire with the yellow band over to the positive side (left in the photo). I can see the + and - in your photo. _________________ 1970 VW (owned since 1972) and 1971 VW Convertible (owned since 1976), second owner of each.

Cool that worked!! thank you!! its truning over but its not gitting any fuel to the carb. just put in a new fuel pump. the red wire in the new pics are the same not sure if the 1 gitting split goes some where else. the guy at the vw shop is the 1 who set me up with the wire and said thats what i needed. some of the wires where broken off after the fire so its was hard to back track em.

Tachometer wire also goes to the negative side if you are running one. |

That "split" wire...one side goes to the choke like you have it, the other to the idle cutoff solenoid on the carb. That's why you're getting no fuel.

I dont have 1. i think i didnt install the point right. took of the distib cap and saw that the rotor is faceing the other way when TDC. tried to get it to face the right way cant get the distib back in,can only get it in when faceing the wrong way. allso tried to get the spark plugs out and the caps on the in side if the wire plugs(2 of 4) where broke and stuck on the ends of the plugs. im allso haveing a hard time gitting the plugs out. |

Likely just at TDC for #3 when you thought you were at #1. Have a good look at the green points wire adn replace the points/condensor with your spare pair.
Investing $35 in a dwell tach would be money well spent. Buy this one.....

Yeah that looks like #3 tdc. Vacuum port on the manifold for thermostatically controlled aircleaner is not plugged. Is this an auto-stick car? Is the egr port completely sealed? |

EGR= Exhaust Gas Recirculation. Just a smog device. |

Keep in mind that the TDC notch on the crankshaft pulley will go around 720º as the distributor goes around 360º. If you don't believe me, turn the engine over with a wrench 2 times and watch the distributor turn once.
You are likely at TDC for #3 cylinder. When you put the cap on with the TDC notch at TDC, the rotor is pointing at #3 ignition wire. Put the wires on following the firing order of 1-4-3-2.
Is the green points wire all burned up? If you hooked it to the wrong side of the coil it is likely to be. If it is, replace both the pioints and condensor. |

The rectangular surface at the base of the manifold (front pointing right at you when you look at the carb/manifold) where the carb bolts up is where the egr valve would have bolted up to. Since the egr valve is missing, you need to make sure that the port is sealed to ensure there is no vacuum leak there. Also there is a port on the manifold left side just below the carb which is for the factory air cleaner. If you don't have the factory air cleaner, the port must be plugged as well. |
