Hi All
Me again..........
So, was taking the car to have the carbs set up this morning, got about a mile and a half and it stopped. Started popping and then one final pop/fart noise and it died.
The AA (recovery guys in the UK) came and found no spark. He thought the distributor had failed - removed it and it seemed fine. Then he thought maybe the distributor drive gear - we removed that and it seems fine, the gears are good, it seats properly. We did get a spark but not a reliable one.
He thinks it could be the drive gear on the crankshaft that has failed and the lack of drive is causing the problem to the drive gear and on to the distributor........
My questions I guess are:
1. Is this likely/possible? Would it just fail with no warning?
2. How is it possible to check, or isn't it?
3. It sounds like a full strip down again.......tell me its not although I am pretty sure it is
4. Any other explanation for the fault.........?
Any help appreciated - I was planning on taking the car to Le Mans in 3 weeks which looks unlikely......
Thanks
Ben
Be careful to see that the points are operating properly in the distributor I've seen the phenolic rub bar worn down and not operating properly at all...
Condenser! Won't run if it's fried. Btw, is a recovery guy a tow truck driver? If so, he doesn't know crap about your 914
Time to work the basics.
Only 3 reasons an engine won't run:
No Spark - easy to check.
No Fuel - easy to provide via starting fluid
No compression easy to check with compression gauge.
Everything else on the engine is function of providing the 3 things above in the proper sequence.
Work though the basics in the order listed. Popping & backfiring noises are a result of spark coming at the wrong time (i.e. timing & dwell) or wrong fuel mixture.
Guessing doesn't work. Get a shop manual - doesn't have to be factory manual. Haynes is fine.
Agree that sounds electrical, and condenser is a good place to start.
The AA guys in the UK are actually much more mechanically aware than what we see in the US, not uncommon for them to fix roadside issues actually.
Thanks for the help guys.
I have admitted defeat and found a specialist who now has the car and will hopefully sort it one way or the other......

Keep us updated with pics so we can enjoy it with you.
Hi Ben,
We have AA - Auto Atlanta Dr. 914 George, and AAA Automobile Club roadside repair and AA alcoholics anonymous 12 steps programs. Some of our members could use a 12-step program for buying to many cars or parts to the point where it may be a problem.
Cheers to you my 914 Brother

Here is a link to a magazine feature of the guys doing the work...proper old skool engineers, amazing what they do

Hope the link works
Same in my country the AA guys are usually highly trained mechanics,generally guys that have a lot of experience,the AA roadside service is a lot smaller and has less guys on the road due to cars being more reliable these days.
