Just wondering if the impulse coupling for the mags messing you around .
I got a fordson E27n long horn here Its 12v but if I spin it on the starter, like starting a modern car or tractor. It turns over to fast for the
impulse to work properly and don't even fire. If I hit it in kinda a short Hit the button then let off, it will fire right up. and same If I feel
energetic with the crank handle. I think the impulse on that one doesn't like a fast cranking speed it kinda overrides the mechanism.
is this why its throwing the timing out to, or is there accumulated wear in the timing gears that after a turn it's out a hair. The fordson major
diesels will do this if the gears are worn.
Have you actually checked compression now as a moving piston will move some air but with a plug in it bypasses , the rings could be stuck.
Are the plug wires shot if . I had a non start sometimes on
that long horn but the wires showed a spark with plugs out, some times it would run nice then ruff, or not start again but pop. I put new copper
plug wires on and it cured it.
After massive cranking and removing plugs are they looking wet, if not the fuels not getting up to the cylinders either. if they are wet you either have fuel or water L.O.L are you sure you don't have water in the gas.
I had this happen with a customers swather once . it ran perfect until he fueled up. The water was in the bottom of his fuel storage tank, then it filled the carb with it.
Just guessing here but It's odd stuff I had problems with in the past. Basically you could have quite a few issues due to the original problem plus the standing for 10 years on top.
Guessings all we can really do without being there.
Regards Robert

Today's Featured Article - Tuning-Up Your Tractor: Plugs & Compression Testing - by Curtis Von Fange. The engine seems to run rough. In the exhaust you can hear an occasion 'poofing' sound like somethings not firing on all cylinders. Under loaded conditions the tractor seems to lack power and it belches black smoke out of the exhaust. For some reason it just doesn't want to start up without cranking and cranking the starter. All these conditions can be signals that your unit is in need of a tune up. Ok, so what is involved in a tune up? You say, swap plugs and file the points....now tha
