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

There are some vagaries about which sensor you should be using, but 4000 ohms is probably on the high side with an ambient temperature (car cold) of 60 degrees. If it's colder (e.g., 40 degrees), then that is not necessarily way out of normal range.

What makes you think it's running rich at this point? Did you get the other things checked (dwell, timing, dizzy cleaning, etc.)?

Changing the CHT is a bit of a PITA the first time you do it, and you have to do it very carefully or you can bugger up the threads in the head. Basically you need to get a deepwell 13 mm socket inside that hole in the tin. Your options are either attempt to stuff the wire lead up into the deepwell socket OR grind off the corner of a short socket extension so the lead can go out there. You use the same tool when installing the sensor, but again, need to be VERY careful not to cross thread.

Again, I recommend reading this page, particularly all the parts about CHT (it's covered in several places): https://members.rennlist.com/pbanders/DJetParts.htm
