Refitted the fuel injection to my 1.7 but cant get the car when stationary to rev over 3000 revs,didn't try to put it in gear and drive though
what can this be
Thanks Brian

Longshot, but do you have a rev limiting rotor in the dizzy?

It will have a spring on the top. If they get worn out or damaged, they can limit revs well below the original design (5800 ??)

No it's the standard one , but thanks for the suggestion

Have ya'll confirmed the basics?

Timing
Firing Order
Fuel Pressure (while running)

How about a drop of 30 wt oil in the center of the dizzy shaft, to lube the advance weights? Should be done annually. If the weight stick, you have kinds of drivability issues, some like you describe.
