Strange symptoms..

This is a list of what I have tried

•points & condenser

•gearbox fluid level

•checked plugs & Leads

•new coil

•changing throttle lift

•changing kick cable both shorter and longer removed crimp

•pulling the choke at during the fault to test mixture

•check needles & floats

•balanced carb air intake

•checked timing

That's all I can remember like I have said I am at a complete loss I have run out of ideas.
 
I'm afraid I'm still stuck at the ignition system with this one.

Just to make quite sure, this is a V8?

The V8 is extremely sensitive to poor ignition system components. This results in cross firing - the spark appearing somewhere it's not supposed to.

Checking the plugs and leads isn't good enough, they need renewing. The leads with top quality ones that won't be available at a motor factor. If you've got a deep pocket then Magnecors, if not then SimonBBC.

I still think a highly likely cause is the capacitor, I can't imagine why you are still trying to use points when electronic ignition can be fitted for around £35. I regard this as an essential to get the best out of a Rover V8.

Again, rotor arm and cap need to be new and good quality. SimonBBC tops the list of bangs for bucks here again.

I'm unclear what you mean by "changing throttle lift"?

Once we have new components in the ignition system then we can move on to talk about the fuel system. It seems much less likely that this is the cause, but some of your comments suggest all may not be set up correctly there too.

So do some real work on the ignition system and then we'll see where we go from there. I'm afraid fault diagnosis on any car doesn't come for free unless it's quite blindingly obvious. You simply have to eliminate each element of each system in turn by renewing with high quality new components. Modern cars have swopped relatively cheap individual components and a lengthy diagnostic process for extremely exopensive parts and a laptop. Personally I prefer the Rover way, you do actually get to find the cause of the fault as opposed to merely discovering that it goes away!

Just ordered electronic ignition new cap and leads and arm from simonbbc here Tuesday will fit and see what happens

Hello Harveyp6 if I remember correctly you have some experience fixing these boxes :wink: do you have a shop somewhere so that I can come and show you the fault the best I can describe it is that although the gears all work and appear to change at the right time if your heavy with the throttle she gets to a certain rpm and then stutters along at the same rpm even if you engage kick down like i said I think it's time she saw a specialist that knows what I should do be it new valve assembly as one specialist suggested or if it is a governor thing (can't remember what it's called) or something as simple as this cable.
If you can help please post me or pm me your number and the best time to reach you.

Missing a trick here somewhere, reading this post again, especially the bit where a certain RPM and stuttering is reached, you mean this only occurs when you are at higher speeds, and it is not evident any other time?
You are scooting along with no issues, then A ) you want to scoot faster and it happens?, or. B ) you are scooting along, you reach a certain speed with no excessive prompting from the gas foot and it happens?.
If it is A, then I would say fuel.
How is the fuel tank?, have you noticed any discolour with the fuel?, lots of bits in the filter?, If the fuel tank has a lot of crud inside it, and it is at a level near the pick up, it could be restricting the fuel flow when under pressure and suction to supply more fuel.
On another note, your first post mentions that the gearbox was replaced for a used unit, was this problem evident before this change happened?.
Still points to fuel problem in my mind, not transmission, don't forget your car has probably been up on strange angles during the tranny swap, thus sloshing the crud ( if any ) around in the fuel tank.
 
The problem is its both a and b can be scooting along at 50 and have it happen or can happen when I want to scoot faster but under both conditions the fault is not effected by changing gear kick down or by pulling the choke out.
 
If you press the loud pedal, and Scottie says I'd like to caaapin, but Ive no go the powerrr, then you need to focus on the engine issues as pointed out in the replies that you have had.
Was the problem evident before the gearbox swap???.
