What went wrong?, it was running great and then not at all Options

[Type 47]

so we put the original 62k engine back in that had not had the distributor removed. Adjusted the valves (again after we put about 10 miles on it) we rebuilt the Webbers and it fired up. We did some timing and tweaking on the carbs.

It ran OK but a little shy of perfect. I replaced the wires and it seemed to improve it but idled a little high around 1,200.

My son came over to work on it the next day, but I wasn't home. All of a sudden, it won't even run.

we swapped distributers (both 009's) with the parts car, then swapped points (adjusted to 0.016). no improvement.

tested spark to all four cylinders. I seems like it's really out of timing but we didn't change it much. (except for the fact that we took the distributor out)

my son says we have spark, too much fuel, and not enough air.

What do we do next?????

How did Porsche expect technicians to be able to set timing to 7.5 advance at 850 rpm as my timing sticker states?

1.8L engine has a 7.5 degree timing mark on the impeller.

At this point with so many parts having been swapped mix and match on 914s you’re liable to find a 7.5 degree mark on others including those that may have been added at a rebuild.

As a rough approximation 7 degrees is about 3/4 of the distance between impeller blades.

Thanks again SH...
My 75 1.8 blower is still in the car. I have a 73 2.0l core I got from Mark Heard completely apart and it does not have the 7.5 indicator etched on it.
I did post that I was not a 914 timing Guru yet...
Guess what, I was RIGHT!
And now I'm a little bit smarter because of this thread.
