Subject: Effect of the Advance & Retard Lever
Chaps,
Had a disappointment yesterday. I went for a first drive in my new Lagonda yesterday and failed! Well it started perfectly after a few strokes of the KiGass but was running very rough. As it was a first drive I was concentrating on the centre throttle, mirrored gears and generally familiarising myself with the controls. Fortunately I keep it on a farm with a massive yard and long drive where I could play. Unfortunately it was only running on about half of the cylinders and despite warming it for 5 mins and running it up and down the drive I couldn't get it to clear. The farm owner was in a rush and wanted to get locked up and I wasn't dressed for getting oily (my wife was with me) so we decided to leave it for another day.
Last night I started to think of all the possibilities and given that it drove perfectly up onto the trailer to be transported home I was thinking could it be a carb needle dropped out of the piston blocking the jet? Could it have oiled the plugs? Then I remembered the advance & retard. This could easily have been knocked fully one way or the other so my question is, if this were fully retarded would the effect be that the engine would start but not run well? I can't get back to the barn for a day or two now (work) but it's something I will look at when I do.
