1450 with No Spark Problem, I need help please
History: last Spring the tractor stopped running because of a blown head gasket. Last Month I started working on the repair. Replaced head gasket, replaced the compression relief spring, re-adjusted the exhaust valve to correct gap, intake valve was ok. Nothing else was touched. I also, took the engineless tractor to the car wash for a good hosing.
Installed the engine back into the tractor, connected everything, turn key and it will not start.
Here is what I know / have done:
1. I have an inline (light) tool to see when the spark plug receives a signal from the coil. When turning the key to the start mode, I see one spark as the key is being turned to the start mode and one spark when the key is returning back to run mode. I also tried without the tool inline.
2. Tested the coil with a multimeter across the + / - terminals and have continuity
3. Replaced the spark plug wire with another one I had
4. Turn the key to on/run mode: I have 12+ volts at the coil
5. During the start mode I have 0 volts at the coil
6. Replaced the key switch with a different one, same voltages at the coil
7. I took the cover off the points, they are fairly new and gapped correctly, when trying to start there is no spark at the points.
I have been using an AC battery charger with jump start mode when trying to start the tractor to make sure there is enough voltage.
Right now I am lost.
