We've touched on this before but after changing all the filters, plugs, leads, rotor arm, dizzy cap and thermostat I'm still getting the same problems. Starts Ok when cold on petrol but doesn't settle to idle so I assume something is wrong with cold start mechanism. When you give it a bootful to warm her up a lot of soot comes out the back. Hesitates on pickup from idle. When warm flips to LPG ok and pick up is good.
Doesn't restart when warm (petrol only) I also note that the electric fan only comes on when cold and turns off when engine warms up. THis is all starting to sound electronic so I'm stumped.
What have I missed?
