That's funny, my copy of the Bentley manual says this is the test for the 3B engine, and doesn't appear to have such a test for the MC. Oh so relevant.

What everyone really wanted to know was that tomorrow I will be performing this test on my copy of the 3B, with hood/bonnet closed, as the weather will be more conducive to such testing. Today was nice, 70F and sunny. More of the same, forecast. Great biking weather.

No helping going on,

P.S. I would like to acknowledge the intellectual leadership of Chris Miller in the field of paper-clip accelerator pedal cover repairs, I had read his original fixit note before having occasion to effect this repair myself. Was going to put that in last night's writing but I got soo sleeepy....
