Mate's EJ. Stock Grey motor & 3 on the tree. Since my dwell meter has died, I gapped the points by feeler gauge at 17thou, set the timing on the marks.
Idle is fine, but above idle there is a massive miss, to the point where if you kept the throttle in the same position it will die. Accelerator pump is squirting fuel fine.
We're both thinking carby issue. Any thoughts? It's like it lacks what ever delivers fuel between the idle & when the main jet kicks in. I'm so rusty on carbies, I've forgotten if there is a power valve on them? Intermediate jet?

Thanks in advance,
Chris

.017" is a bit on the high side, so maybe the dwell is a bit short, particularly if other components in the ignition system are a bit sad. The spec, if I remember, is 012"-.016" point gap.
There's probably something else going on too, but worth a try.

It could be a distributor issue.

It sounds like you are loosing spark as vacuum advance comes in.

Try disconnecting the vacuum advance pipe (temporarily) & then bring the revs up.

I've had issues similar to this caused by faulty advance plate earthing.

If at first you don't succeed, just call it Version 1.0

Thanks Terry. I'll suggest that, though I doubt we'd be getting much vac to the advance, as we had plenty of throttle open.
I might try a piece of pipe on the vac advance and give it some mouth vacuum and see if we can duplicate the problem that way.


Cheers,
Chris

I has an FE 40 years ago and the lead on the advance plate was broken inside the sheath so when you got to around 50mph it would die and when the speed dropped it would take off again. Check it out? Good luck.

Turned out to be the vac advance. "Full of crap" is how it was described to me. Thanks for all your advice, much appreciated.

Cheers, Chris.
