Took my new (to me) Dasher 1.6na out for it's first spin yesterday. I noticed that when I accelerate, the response is very mediocre unless I put my foot almost to the floor. The car never hesitates or stumbles, but compared to my long gone 78 Rabbit gasser, acceleration is very slow unless I almost floor it. I know this is kind of subjective - it acts like the fuel flow increases maybe 25% during the first 75% of pedal travel and then goes from 25 to 100% in the last 25% of pedal travel. This is my first diesel and I'm wondering if this is normal or whether something is amiss. The car has new injectors & no air bubbles in the clear line to the IP. Transmission is a 4 speed. I sure could use some feedback on this. Thanks!

Make sure you're also getting full throttle cable movement, not partial cable and partial cable jacket movement. Likely if this was happening, it would mean sluggish and not getting full throttle, but something to just check quickly.
Everybody else lists their cars here - but not me.

... and make sure the accererator lever is going all the way to the stop when you floor it.
I got an injection pump off an audi 4000,
had the 1.6 diesel, sits the same direction as your dasher.
I put the pump in my Rabbit and it acted the same way.
I always figured that's the way it was supposed to be,
smoothest takeoffs of any car,..
and it has power if I step on it.
I figured it was a special governor spring, for the fancy Audi.

Many thanks for the advice & suggestions. I will make the checks noted. The way it's working now isn't causing a problem - just different from what I'm used to.

It turns out that I did not have full travel on the throttle. The throttle lacked almost 3/8" of hitting the full throttle stop. Cable adjustment solved that one. Thanks to all for the help.
The bad news is that it looks as if I have a rather nasty leak from the IP main shaft seal. The timing belt is soaked with fuel and the pump sprocket has fuel all over it. The rest of the pump is dry. I'm not too concerned about reasealing the pump due to all the good info here. I'll order the seals, belt & tensioner and probably pull the pump after Christmas.
