ok will try that.after a bit of googling seems the reed switch is a magnetic switch.found this on a site

A Reed Switch consists of two ferromagnetic blades (generally composed of iron and nickel) hermetically sealed in a glass tube. The blades overlap internally in the glass capsule with a gap between them, and make contact with each other when in the presence of a suitable magnetic field. The contact area on both blades is plated or sputtered with a very hard metal, usually Rhodium or Ruthenium. These very hard metals give rise to the potential of very long life times if the contacts are not switched with heavy loads. The gas in the capsule usually consists of Nitrogen or some equivalent inert gas. Some Reed Switches, to increase their ability to switch and standoff high voltages, have an internal vacuum. The reed blades act as magnetic flux conductors when exposed to an external magnetic field from either a permanent magnet or an electromagnetic coil. Poles of opposite polarity are created and the contacts close when the magnetic force exceeds the spring force of the reed blades. As the external magnetic field is reduced so that the force between the reeds is less than the restoring force of the reed blades, the contacts open.

reading that it seems the circuit needs to be closed(fuse in) for it to not retard the ignition.am i reading it right.also do u know where the red?blue wire goes as mine doesnt seem connected further down the loom.sorry for all the questions but everytime i touch automotive electrics things seem to go wrong lol

no you're reading it wrong

This is a speed limiter device, when the speed hits 55mph the magnetic field closes the switch (I think) and closes down the pv somewhat....That's how I see it anyway. For the last time...try disconnecting it!!!

I also checked the powervalve was in the right position today.after turning ignition on the powervalve is sitting about half a cm away from keyway could this cause same symptoms

when you turn on the ignition key the pv goes through a cleaning cycle (sounds like zzzt zzzt) then comes to rest, the 'U' slot in the pulley should now be directly in alignment with the blind 4mm hole in the cyl head, use the two cable adjusters to achieve this and take care to leave enough slack in the cable so as to not stress the servo

All adjusted will take it for a spin tomoro and see if its made a difference. Is it usual for the left cable adjuster to be set alot further out than the right one.as thats the only way I could get the hole to line up
