Pres-

Please read entire message. I think you are rushing things.

Now that you've replaced those components (you used a .o15" gap for the points correct?) pull #2 or #3 plug wire off its plug and place it on an old plug. Ground the plug against the block and check for spark. As others suggest, I'm not sure you have a spark problem, but perhaps compression or fuel supply problem.

If you get a whitiesh/blue spark, then do as Dell suggests with the oil in cylinders AND spray some WD40 or engine starting fluid in there while at it. Replace plugs and try to start. If she fires for a coupla seconds, you have a fuel supply problem. Could be gummed up carb, old gas, clogged fuel filters (there are 3 of them), leak in manifold gasket or any combo of above PLUS a possible compression problem.

On a tractor that hasn't run in 3 years, I really don't recommend you try to start them up without some detective work first: 1) ascertain WHY she quit 3 years ago - will tell you a lot 2) change oil/fluids EXCEPT hydraulic fluid - no need to spend that time and $ until you know your tractor's gonna run 3) put Rislone/MMO in cylinders and in the oil galley and HAND CRANK engine for several revolutions to free up rings and to prime oil pump 4) check/replace all 3 fuel screens 5) remove old gas/flush gas lines.

She stopped for a reason and that reason could be anything. Don't want you to damage an otherwise good tractor by rushing things.

Presley..... ...squirt about 1 oz or tablespoon of regular engine oil down all yer sparkie holes to seal the rings so you get compression so you can start. Always change out your OLD GAS as it has turned into varnish clogging carb goop..... ..Dell

Points & Condenser???
Also check thru distributor for ground -- stud insulation may be gone or copper thingy may be touching somewhere.

Wired wrong?? bad switch ?? try this, run a wire from the battery to the coil then check for spark, or in other words hot wire it. If that doesn't work take the hot wire loose and hold the coil wire the one to the cap next to metal of the tractor and then take your hot wire and put it on the coil on and off and see if you have spark if so you have points, condenser problems. Hope this helps
