Try putting on a new condenser and be sure the gap is set correctly. If it is not the condenser, its most likely the coil. Andy.

You need to pull the cover off the coil and take a flatblade screwdriver and touch those magnets to see if they still have strong magnetism. The magnets are what creates the spark when passing by the coil. The magnets should attract that screwdriver with a lot of attraction. If they don't, that's probably the reason there's no fire. Make sure the points are gapped at .013"
and since you have cleaned the points take a cotton swab dipped in alcohol and clean the points several times. Pull the coil wire from the
cap and hold it within 1/8-1/4" of good ground while some cranks over the engine. Should have a hot blue spark.

If the magnets check out ok I would replace the condenser to eliminate it. Make sure the kill switch is in the run position. I would disconnect
it at the mag for now. The coil could be getting weak too. You don't need to pull the mag to replace it. Hal

Thanks Bob, Hey someone posted an H parts manual on here before, had the same layout, but when I tried to print off some of the pages, the print size was all messed up, Any Ideas? Are there othere manuals such as this posted somewhere?

Thanks, Gene

I've had the same problems with size when printing.

My HP printer has a "print preview" function, where you can see the page on the screen, as it will print, and then make changes.

There's a few more various IH manuals on-line at Rudi's Cub Page.

Install new points and condensor and be sure the impulse coupling has a good snap to it. If it still doesn't work put in a new coil. Magnets seldom go bad.
