Will it STAY running, at higher idle or say, at 2000?

I’m wondering about the reeds. I know they are buried but if you take the carb off and look carefully with a flashlight, you can see some of the area. You can also feel around in there with a 90 degree pick, to see if they are closing all the way or if there is a chip off of one. The good news is that with a Mark 10, there are only two reeds per cylinder and they are towards the front of the crank case.

What’s the AJ number on the carb? Could somebody have put on a different one, trying to “improve” it? I might have another one kicking around someplace.

Long live American manufacturing!
