914 1975 1.8 on twin carbs running poorly

[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?

To me, it sounds like a timing issue. Where are you based? It sounds like the perfect candidate for a session on a rolling road.
My 914 was the same - it would barely pull 70mph up some hill on the A30, and needed to drop down a gear or two.
Rolling road session shoed the timing was well out – I think this is common on US imports as a) the fuel in the USA is crap and b) timing is messed with to get the cars through emissions.

Im just on the outskirts of Leeds, it would be good to know if there is a reputable outfit in my area that could diagnose

I have to agree sounds like a timing points issue.

PS 3.5k in third gearbox can't be 30mph?
