[AJD] JD 70 running rough

[Troy Bogdan]

Thanks John,
I was thinking along those lines.  I already looked under the dist. cap, and 
there was a little bit of carbon, but I didn't clean and re-gap yet.
I'll probably try that.  Otherwise, gas is fresh, and the carb was re-built 
a few years ago.  Thanks for the help,  Troy
