Buzzer chimed in.

I`ll stop if it bothers you.

If it bothers him...keep it up.

Hahaha it's all good, I was only poking fun. I'm incredibly grateful to everyone that's been helping out with this hellish ignition debacle.

WE HAVE A WINNER!

I'd said recently that I would post an update shortly as there was something pending.

After having a chat to Liam at Fast Bike Gear, he'd contacted Ignitech and found that there was a better unit for the job. Liam arranged a replacement for me that is far better suited and looks like Buzzer's one.

I fitted up the new one and started getting popping and backfiring.  The previous unit didn't so much as cough. My readings I'd posted earlier were no longer as outlandish as before, so I knew this thing was definitely a step in the right direction.

After $15 of Skype credit, bugging Liam on the phone and picking his brain regarding tooth settings, we checked the timing with a light and confirmed the plugs were firing at the right point.

It wasn't until about an hour after I spoke to Liam on the phone that I had one last thought. I'd been playing around with reversing the coil output plugs on the last Ignitech, switching back and forth when troubleshooting it.

I swapped the wires leading from the Ignitech to the coils back over, gave her a little squirt of fuel into the carbs and cranked...

It sputtered, caught its rhythm and roared into life.



SO, a few tips for future lunatics that want to run a 620 (and most likely other FI Duc engines) with carbs:

- make sure your carbs are good (I'd already rebuilt mine)

- You need an Ignitech TCIP4 v88 that has the cam/crank sensor plug. Avoid one of the 'universal' units as some don't read the individual teeth properly and spit whacky figures out

- to wire the unit, follow this list: <PLACEHOLDER>

- Check, double check and TRIPLE CHECK your wiring

- pull out the spark plugs and check for spark

- This is one of the most crucial: check with a timing light. It'll tell you straight away if the spark is firing when it should. If it is, then check your signal to the coils from the Igni and swap it over, just to be sure.

Thank you so VERY much to everyone that's offered their tips in this thread. You have no idea how grateful I am to each of you for your help. Thanks also to Liam from Fast Bike Gear for helping me get this thing going. The guy really is a mad scientist when it comes to these bikes.

I'll likely start up a separate build thread shortly as this one small saga has been part of a bigger restoration project.

Would you clarify this?

The place holder is for me to put in what wire goes where and possibly include images, just to make it even easier for anyone else that's treading this path later.
