First thing is that the choke(enrichener) lever is sort of confusing.The enrichener is "on" when the lever is down flat, and it is "off" when the lever is up on an angle nearest the tank. This is opposite of the way most people think it should be, so I always mention it.
Ahh. That is opposite of what I was doing. I pushed the lever down so that it pulled the pin up from the carb....but the lever seems to want to stay in the down/flat position, almost as if it was spring loaded. It doesn't seem to want to stay in the angled position. Plus there is a second, smaller flat arm that is right under the lever marked 'choke'...it doesn't seem to do much but it does move freely. Is that normal?
Hitchcocks sell starter motor blanking plugs or a kit to install a non es primary cover.
I would take the carb off, remove the jets, clean it out real well in all the little orifices, and re-jet appropriately.
I've already taken it off and soaked the jets in carb cleaner; they look to be clear with no residue clogging them. I couldn't see any markings indicating what size they were, but as small as they I could have missed it.Any idea what sizes would get me in the ballpark? Engine is stock internally, with the "classic exhaust system" from our host and a K&N filter. (previous owner had the stock airbox mounted; it was stuffed with what looked like a big hunk of scrubbing pad!)
