Looking for help with timing ignition in Calgary

[HombreCalgarian]

Have to admit - I am close to zero when it comes to older distributors, setting ignition timing and other wizzardry from the era that predates electronic/plug-and-play tech.

Now, being in the final stage of my Sniper EFI saga, I encountered a situation when I need somebody fluent in the above stuff.
I am sure I screwed the distrib timing since the first attempt to start (after all the presets were complete) ended in backfiring into the intake.

I wonder if somebody could stop by for 30 min - 1 hour (I am open to any reasonable form of appreciation ) to help me with this? I do have all the tools (timing light, vac/pressure gage, etc.), but lack the knowledge and after this little failure - self-confidence.

Thanks in advance!

DID you or are you using a distributor type which is compatible with the EFI system? Key point, as I understand it. A solid and consistent spark trigger signal is important for the correct signaling of the EFI system, which might not be good enough without one of their recommended distributors systems. Are you letting the EFI system control the timing and such? Might need to consider purchasing a later-version Lean Burn distributor which only distributes the sparks, without performing any timing advance generation functions? Or purchase a distributor (from their list) and make it look as much like the OEM distributor as possible. Please let us know how it works out.

Just some thoughts,

Of course, it is all from the Holley set - magnetic distrib, coil drive, etc.

Dizzy off by 180 degrees?

Thought of that, but rechecked TDC and the distrib orientation. Not this, methinks.

All figured out myself. Topic can be killed. Thanks.

Glad to hear of your success. Interested people want to know what it was you figured out.

Just another proof of my eternal imperfection. I ran the spark plug leads on the distrib cap clockwise. Once fixed, started right up.
Found the tip in one of the "typical newbie error lists" somewhere.

Glad that you fixed it.
We all make mistakes and welcome!

Glad you figured it out! There's a thread out there (that's a fair number of pages long) of all our mistakes - there's some good ones!! It's worth a read just for the laugh!
