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?????

Yep, I'm sorry I may have added to the confusion.

I'll never retract something I post in error. I'll allow my lack of knowledge to be in full view of all.

I will apologize and re-post if I'm wrong, however.

You should notice that I was damn close to what the timing should be at that RPM.

I posted 25+degrees at 3500 rpm. I was 2 degrees off!
I just pulled that number out of my knowledge base in my memory.

Red mark is 27 and 0 mark is TDC.

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

I wasn't aware of any timing lights that could do advance back then...

I started doing this stuff professionally (all this means is being paid) in 1982.

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 for posting this.

Is there any difference between the 1.8 and 2.0?

the pic below is the actual impeller from this engine. It had some broken fins so we swapped it with another one from a spare 2.0. Nothing but the 27 line, no 0, no 7.5 mark.

The impeller we put on it was from GA006291 a late 73' 2.0 I believe. It has the 0 and the 27 mark. I will have to look closely at it, now I know where to look for the black line.

I hear what your saying about "at this point" I do believe this engine is original to this car; both have low production #'s 00696 for the car and GC000243 for the engine.

Then again it had a degree plate on the front of the engine like a bus would have.
