1975 1.8 on twin carbs running poorly Options

[dt4]

My car is now registered over in the UK so I can enjoy it at long last, I took it out today for the first time other than the short drive to the MOT centre last month

It drove OK to a point but I noticed it was very slow to respond once in 4th gear, it felt very flat and not at all keen to pick up speed
If I shifted from 3rd to 4th at around 30mph / 3500rpm it was sluggish and a just over 30mph in 4th it felt like it was in the wrong gear and needed to down shift back to 3rd

on the hills it soon ran out of grunt and I was having to down shift from 4th to 3rd and even 2nd to get it to rev again and build speed
Setting off on a hill I had to really increase revs in 1st before shifting into 2nd otherwise it would bog down and feel like it was stalling

thoughts:
fuel?
timing?
other?

thank you

IDF carbs? Size? The interior of that distr is pretty dirty.

I shall have to get more involved in how these things work, I don't know how the distributor mounts or how the rotor arm is removed. Ill spend some time reading the Haynes manual and then start with the plugs and work towards the coil.

Are there adjustable points on these?

thanks

Looks like an electronic ignition module of some sort is installed. That little black box just under the rotor looks like a pickup for a Pertronix style ignition. Also can see a red and black wire tucked in under the rotor as well. Those would go to the pickup of the ignition.

So no points or condenser in there. But as mentioned the advance plates might be gummed up. But you’d probably feel that in all gears and anytime you stomped the accelerator.

But as Kevin said, it looks dirty in the distributor. Would t hurt to clean it. You can check the advance plates while you’re cleaning the distributor. Rotor just pulls off (pull it straight up).
