Dark deeds.
Fareastdriver and airborne artist,
Yes, the dual-tank would have been one solution. I remember a yacht, you cranked up on petrol, by the time you cleared the harbour mouth it was warm enough to go over to paraffin until you hoisted sail.
No, it was simpler than that. (Reluctantly shooting another of my foxes) Procedure:- Open (side-opening) "bonnet", very simple carb, fixing bolts (two) off float chamber in a few seconds, remove chamber, chuck out contents, fill with "Ronsonol" lighter fluid (from any tobacconist), replace.
Swing vigorously on bent wire * in front, thing should fire-up from cold. By the time it had worked through the Ronsonol it would (usually) keep running. Of course, you always had to keep a bottle of the stuff in the car.
* Why, oh why, don't we still have 'em ? So useful !
Having confessed to a felony (or at least a misdemeanour !),
Danny.
