1.7 d-jet '73 almost running Options

[isdyl]

Hi all - so I've refitted d-jet on my 1.7 which had a single weber when I bought it. It's almost running but I've run out of ideas as to what to adjust or check. I've recorded a video of it starting. You'll hear that it starts quite lumpily and wants to stall. I manage to get the revs up by feathering the throttle and they go up to 2.5 or 3000 revs on their own for a second, and then it all dies again. I can keep it running by feathering the throttle again.

Fuel pressure when running is 2 BAR. Theres no cold start valve connected. All injectors are 'squirting' as I took them out and checked in a jam jar. I've tried adjusting timing, mixture screw, air screw. I haven't checked the valve clearances yet but have had the distributor in 100 different settings with no improvement. I just wondered if anyone has any ideas please?
Thanks, Dylan

Go ahead and take out and clean the dizzy as Porschetub suggested. Take it apart and do a thorough cleaning and lightly lube everything. Check the ground strap between the two advance plates. This is all good maintenance.

I'm not sure the advance arm moves much even when operating properly (IMO it's not a very "gratifying" movement, so to speak, and hard to tell). It could be your problem, and I'll defer to others if they think that, but I generally put this in the category of "drivability" issues (unless it's really bad).

Did you get a dwell meter and set dwell properly? Then, are you confident you know TDC and the timing marks? If it won't stay running without revs, get someone to help you keep it running while you get the light on it.
