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

Just a thought - you have flow when testing the injectors off the car by are you sure you are getting flow when on the car?

Question for the brain trust here - does his set up have a cold start injector or any other way to getting fuel to the car outside the four main injectors?

Hi - there is a cold start injector but it’s not yet plumbed into the fuel hose that runs past it between cylinders 2 and 4. I did wonder a bit about fuel pressure and flow as I only get 2 bar when the pump is running. As soon as it stops running (like when the engine is off) the gauge drops to about 1.2 bar. I assumed it’s leaking back past the pump. D

fuel pressure should be between 28 and 31 psi. probably your fuel pump need replacement or getting low voltage.
