Honda ATC90 no spark

[matt]

I just picked up this 1976 Honda ATC90 earlier this week for $125.00 and it didn't have any spark. So I replaced the points and it fired right up on the first pull. It ran for about 20 minutes I shut it off then I changed the oil and started it again it ran for a couple seconds and now it doesn't have spark.

Have you rechecked the points? what about the plug?

[matt]

The plug is brand new. What do you mean by rechecking the points? What's the air gap supposed to be?

Somebody has to know something about my 90? The points are brand new, I just took the coil and condesor to the Honda dealer and they said it tested ok.
