This manual should help you http://gardentractor...-repair-manual/

To verify breaker point condition, remove the screw retaining the points to the breaker point box wall. Remove the scew holding the flat copper wire and condenser lead to the breaker point assembly. At this point care should be taken when removing the points as the eccentric adjustment screw will be free to fall from the breaker box. If a multi meter is available, set the meter to read "Resistance" (ohms). Place one lead on each side of the points and read the resistance. High resistance will be indicated by a high scale reading. The higher the scale reading the higher the resistance and the poorer the spark will be. If high resistance is indicated, but the wear is not extreme, cleaning and regapping at re-installation will likely cure the problem. With a finger nail file (emory board type), slip the file between the points and gently work the file back and forth to burnish the points. If the damage/wear is extreme, replace the points with a serviceable set (available from a variety of vendors listed on this site).
One other simple item to check is the flat copper lead connected to the points where the condenser lead is attached. On occasion, the flat lead has been known to ground against the breaker box cover causing the ignition to short to ground. If you have spark with the cover off and non with it on, then that problem is easily resolved by use of a small needle nose pliers to bend the flat lead slightly so as to no longer contact the cover. Great care should be excersized when bending the lead as they can be easily broken.
Good Luck!

Hi Bill this tractor has a magnito is there a test procedure for this?
Thanks
The manual I posted a link to in the first couple posts shows testing procedures on the magneto.
Since it has been sitting outside in the elements I'm guessing there is a good chance the magnets are rusty on the coil and flywheel.
To be sure you will have to pull the flywheel off to inspect and clean up the contacts.

Check with Jestin at www.tubeframes.com
He's in NH, and can supply a kit for re-building it for $20.00.
Or you can do what I did, and exchange your old carb for one that is already re-built. That's a bit more $$, but I wasn't comfortable with trying to rebuild one on my own.
I've done a decent amount of business with him, and he's always been easy to deal with and very reasonable on pricing.
