Hi all, i'm new to posting here but have been reading for quite awhile so hopefully this post is in the accepted format. thanks in advance for any feedback from your collective knowledge as well.
So here's the problem that has me and every mechanic in a hundred mile radius baffled. i have a 1962 John Deere 2010 with the four cylinder gasoline engine that hasn't run in about four years because it melted down the ignition system one night. i will also mention that this is a reverse polarity system still with a positive ground. Now everything has been replaced and has a good bluish white but intermittent spark and will not start even with a spray of ether. it has a new coil, condenser, points, cap, rotor, dust cover, spark plugs and wires. the coil is getting proper voltage, the points are gapped at .020" per the john deere manual, the points have a small spark while cranking when they open and the circuit is only grounded while they're closed so no short to ground in that leg of the circuit and everything ohmed out correctly. I tested the coil while cranking and the spark jumps the spark tester with a bright bluish white spark in rapid succession. When checking spark with the tester at the plug end of the plug wire while cranking it produces a strong bluish white spark but it will turn a few revolutions without spark following one or two good sparks regardless of the cylinder wire i test. I appreciate any feedback or ideas. I'd love to get this old thing going again.
