[CDO] Running like a hit and miss

[Roger Garnett]

> Ian K suggests: First clean up the ignition  cam lobe and spring with a
piece of cloth

I do need to go over this again - had to adjust the spring to get contact
to begin with. How long should the contact duration be?

> Second , take out the spark plug , reconnect the lead and place the plug
on top of the engine ensuring an earth contact .Turn the engine over to see
what sort of spark you have and if it is regular.

I've done that, have a decent spark.  (At hand crank RPMs anyhow!)  Spark
Plug is a bit sooty at this point.

> Recheck the timing

I should go through the valve timing process - altho it was recently
running reasonably!

> After that i would have another look at the carb for blockage.

The fuel path is currently all clear, and free-flowing. Great flow if I
pull the line off the carb, or the sediment cap.

> Also check the battery , it could be nearly flat .

Battery is freshly charged.

> Johnny sez: My car has the later 1904 style carb. It would start and run,
but had cut out / hesitation difficulty at higher speeds.  I blocked off
about 1/4 of the air intake to give more velocity thru the carb.

The early carb is very different, not sure what would happen.  I've had the
tube in place running to the "air filter" on the side of the body. Left it
off last night, no change.

> Gary H sez: have a tumbling machine mounted on the wall of my shop.  I
strap a tank to it with about a quart of abrasive tumbling rock and a few
quarts of soapy water.  Let it run for one or two days

Gary - I may take you up on a tank tumble over the winter!
