Gov mod

[zx_volcane]

Isn't there a guide somewhere?

You basically want to take the throttle plate off the top - 10mm nut holding it onto the spline.

Before you undo it scribe it inline with the spline on the top so its relative position is marked.

Whip it off and the spring and two round bits of spring locating plastic.


Then you want to undo the four hex bolts that hold the top hat onto the pump.

You may have to remove the two long stop screws to gain access.

Then you want to wind out the max fuel screw - again making note of how far it was wound in.

You should now be able to pop the top off, I find you have to hold the stop leaver on the front of the pump to one side for it to clear the gov cradle.

Now its time to do your gov mod - and in the famous words of haynes refitting is just the reversal of the above


Probably a good idea to cover the top of the pump with a sparkingly clean rag to stop any crap getting in while you have the top off.

Also those hex bolts are only nipped up, don't wind them right in mega tight when putting back together.

A new top hat seal might be a god idea, they have a tendency to leak after.
