It was a bad wire from solenoid to starter! Which is strange cause I had checked it with 200 amps straight to the starter prior to this. Anyhow it is running now. Smoking a little more than I remember from last time it ran. It also is spitting a little oil into the air cleaner housing for some reason and this may be the reason its smoking? I had sprayed a touch of WD40 in the cylinders as a pre lube but I would have thought that would burn out in just a few minutes.
All electric motors run on amps. If the motor had no torque, it had little or no amp flow.
Amp flow is the sole basis for electromagnetism (thus torque) and it does not matter what the voltage is other than to "pressurize" enough amp flow at the motor terminal to meet crank needs.
Think of a battery like a pressurized water supply. Amps are the gallons per minute and voltage is exactly comparable to water pressure. A bad wire and/or connection is exactly like a high-resistance kink in the hose and restricts flow, whether that be coulombs/sec (amperes) or gallons/min of water. Trivia: One coulomb = 6.242x10^18 electrons.
When the starter is not energized, a full 12v will appear on the switch (solenoid) before the starter terminal. With a bad wire, as soon as the starter kicks in (draws), the pressure will drop very low, if either the hose is kinked, or in this case, the electrons cannot flow through a high resistant bad connection. But you knew this and fixed it.
WD-40 lubes great for the way in which you used it. If the engine is having blow-by issues, it is possible that the dry cylinder walls sat so long as to accumulate a bit of surface rust on them. The rings normally scrape this off, but the debris tends to work it's way into the ring grooves (piston lands) and sometimes the rings stick. They may clean out on their own after a few hours of running but may tend to stick indefinately if too bad. Usually they stick in at the furthest squeeze (usually the little worn bottom of cylinder) and then leak compression towards the more worn upper cylinder thereafter.
It is hard on gas engines to not be regularily driven and very few people mothball them with extra cylinder oil before long term storage. Diesel engines tend to be naturally oily and fair better in neglected storage.
