When ever someone comes on here asking why their tractor don't start, I rarely respond because I only have a couple old gas engines and they always start and run. I'm not real skilled in that area anyway. Flash foreword to today. Time to put self propelled sprayer away for season. Been sitting out for last two months. 172 ci. Ford industrial. Spins over but no start. Give shot of either--nothing so must be electrical, Take dist. cap off, dry. Scrape contacts on rotor and cap, file points. Put together, pull plug, ground plug to frame, no spark at plug. What's next? I hate to throw all the elec. components at it at once because it is just one that is causing problem I'm sure. What should I try next? Thanks, Greg

Follow the electrical path...battery to coil to distributor (condenser and points), to plugs. Since you messed with the distributor, did you disturb anything that might make it ground out? You should have spark at the points when you turn the engine over, or if the points are open, you can find spark at them with a screwdriver. Wires firmly seated at coil and cap?

Do some simple trouble shooting. Most likely still a points problem. Take the cap off dust cover etc. Then turn it on and open and points by hand being careful to not gerund them with your hand. You should see a spark when you open them and if you do not then you found the problem

Check the fuel if it's been sitting there that long

I'm betting points. I'd just replace them and I'll bet it will be running great.

Excellent spark at the points. Nothing at the plugs so it has to be rotor, cap or coil wire correct?

With the points closed, open and close them with a screwdriver and see what happens. Make sure the screw driver does not touch metal when you do this. if there is no spark, use the screw driver to make ground to the points off and on, anywhere on the points will do. If you can make spark the points aren't making contact. The secondary, or big wire out of the coil should make a big long snapping spark while you are doing this. If there is fire at the points but no fire out of the coil then the coil is suspect.

Pull the center wire out of the distributor cap and hold it close to the block and then open and close the points by hand. You should get a spark at the coil wire that jumps a 1/4 inch gap or more

Replaced cap and coil wire. Still nothing at plugs. Whats's next?

May be the condenser. I had that happen to my 54 chevy. It just stopped running. I changed the condenser and all was fine. Stan

Did you drain the carb and check the flow? There is a post on the case board like this.

Be careful -- don't loose that idiotic clip holding the rotor to the distributator shaft.
