Just thinking about LPG.

How do monofuel cars work on LPG where the engine isn't running to warm the coolant before switching? Or more interestingly aircooled engines. I've heard about VWs having exhaust heat exchangers to warm water for the vaporiser, but that doesn't get around monofuel aspect. Are there electrically heated vaporisers out there?

Yes, you can indeed get electric heat exchangers.

Regarding cold running, the Golf could be succesfully run on LPG from stone cold. A larger engine using more gas needs more heat to combat the change in state between liquid to gas. Small engines aren't really a problem.

I was thinking something like a Reliant 850 engine running a dedicated lpg carb (Impco do one that suits "Upto 70hp"), no petrol system at all, not using a Robin/Regal/Rialto chassis though, or any Reliant bodywork at all infact.

It just runs. Fork lift trucks don't have any pre-heating.

Just don't demand 4000+ WOT rpm from cold and it should be fine. From stone cold let it idle about 30 secs so some heat gets to the vap. Excess fuel demand when cold will result in LPG passing the regulator as liquid, may be so rich engine cuts out.

Oh nothing like that. Was thinking if a Kitten or Fox came up on Ebay, take the GRP body off, maybe try to keep part of the original firewall and floorpan. Then make something out of sheet alloy and second hand ebay panels to produce something vagually covered and a little hotrod like. A traditional "Special" as it would have been.

Then use a megaspark with edis for ignition and an LPG caburettor for monofuel LPG. A little engine like that tweaked up a bit to run gas would make a 60 litre tank last months, be sat on the floor and always give me the option sticking on a dinky supercharger like the liege kit cars used.

Being lighter the brakes should be upto it, and with just a body swap it won't need an SVA as it has enough points from everything else being original.

Bit like weekend guys used to when they turned what was Austin 7's into cars that looked like Lotus 7's and the like.

Just need to find one in the UK. Less messy hoses needed. Time to start the planning.
