Alright here is the deal, ever since i converted to carbs i have had my spark plug wires set up like this ( picture ) but it runs crappy and I set the timing but still runs like crap. Now my question is after I was browsing pictures on here I see that it looks like my plug wires are set up wrong. But when i switch them to like this ( 2nd picture ) it just turns over and then ... pops like a timing issue. WTF!

from glancing over this article the only (kind of) mention of finding #1 position on the distributor, was "finding top dead center for cylinder #1". what i didn't notice (and could be your issue) is if the "distributor" is ALSO pointing to #1. a car this old can easily have had the distibutor installed incorrect position at sometime. its possible that the wires were previously repositioned to the altered distributor positioning and when you reinstalled them correctly to factory spec.'s...

I did have the dizzy out at one time but what drives me stir crazy is after the initial install, the car ran great for awhile

and again my question in regards to the first picture is going off this would't this indicate that the plug wires are on wrong?

As far as I can tell, you have them right in the first pic. Webers routinely clog the idle jets after you mess with them- ie remove or install them or the engine.
Try cleaning the idle jets.
Starting with the #1 plug, go clockwise around the distributor cap and it should be 1-4-3-2. You can also go backwards around, (CCW) it's 1-2-3-4.

sounds like too many variables and sorta's.

after messing around with "maybe this is it... nope... maybe that is it", start from the very beginning as much as possible. from what you describe it all started with new wires. i'd make sure the #1 cylinder (on compession tdc) is in cync with the rotor pointing to your #1 spark wire (the rotor can be aligned w/ #1 wire on the cap). if the distribur is not in the factory position, it will still run assuming spark wires are moved accordingly and timing is set to spec's

Amazing. I just experienced this, too (dizzy cap 180 degrees backward). Not in any manual or trouble-shooting guide that I've ever read. Took 3 months and finally a two to the mechanic to realize this. Apparently very unique to 914s...

914 distributor caps have a"tab" that fits in a slot on the top of the distributor. It's impossible to put it on backwards. Unless you have some aftermarket cap! The distributor shaft Tang, and drive gear, are both offset from center. They only go in one direction, unless you have the wrong distributor, or the drive gear is positioned wrong!

Yep; mine has the tab but never knew it. Have replaced and taken off/put on many times as I'm an original owner. Was wondering this time why those spring clips were so hard to snap back in place!

@TheCabinetmaker

No, you *can* put the distributor gear thing (that goes into the hole before the distributor) 180 degrees off (that has the off center slot to match the bottom end of the distributor shaft).

And if you do, your engine will still fire up and run (albeit poorly).

Again, not just the cap but the whole distributor will be 180 degrees off ...

Yep! Backwards, it holds the cap up enough to interfere with contact between the prong on the cap, and the rotor. Thus, running like crap!

Only if the gear is indexed incorrectly! It can be in 5 different wrong positions.

It's all dependent on the position of the gear. Distributor will only go into the gear one direction!

Exactly my point

Happened on my 2056 (which was built by a "reputable" engine builder), which is why i posted "Ask me how i know".
The moral being, don't *assume* your gear is indexed correctly, VERIFY !

Took a good 6 months to diagnose and finally fix ...

Yep; that's exactly what was happening. Cranking but no starting other than some "puffs". Advance module was in right place, so knew I didn't have the dizzy in wrong (and didn't move car w/o dizzy while in gear...)
