Motor has 2 different means to power the coil
Key in ON/RUN sends 12V thru resistor directly to the coil. Reaches coil with around 9V
Key turned to Start sends 12V to starter solenoid. Solenoid energizes and connects power to starter and also sends full 12V bypassing the resistor (Green wire)...
Old guy old term, Be angry, ecstatic, holler , frustrated
I'm not being that, I just don't know how to explain what's happening and why any further. I could put it all on one page if that may help, just think another might do better
When running the voltage powering the coil goes thru a resistor which "should" drop the voltage down to around 9V. There is probably a weak connection in the key switch so voltage jumps around.
It will start without full voltage (green wire) but will have a harder time doing so mostly when cold.
If it takes a while before it happens its not the valve
When it happens, stop the motor. Go to the gas cap and get your ear close to the gas cap, then open the cap. If you hear air suck in then its the tank vent line, might be clogged
TKS carb
The antisiphon valve is connected to the top of tank and has a barbed fitting which the rubber fuel line connects that goes to the fuel filter/pump
If you can start and it runs fine at first even at high speeds and then starts loosing power over some time. Can shut it down for a while...
So long as there is iron and water there will be flakes. In salt water there will be even more
Assuming open cooled. Fresh water and muffs, fire it up and let it run for a while. The whole time its running fresh water will be flushing mans and elbows. Won't happen as fast or as good with...
How was this checked?
My guess is the motor took on water from stopping abruptly. Need to take all plugs out and crank the motor over a few times. If it doesn't start after that, go thru the TBV troubleshooting guide
Check your fuel delivery system. Fuel filter contents in clear container. Disconnect power to coil and remove fuel line. Crank motor and see how fuel comes out, a little or a lot.
That's what I'm saying, the power is coming from the solenoid. The slight spark is normal because it powers the motor back up, same as turning key ON
Figure you have a multi meter. Check for a connection between I and the right side post on the old solenoid. If there is a connection and the...
I've got nothing then, just know how it should work
You removed the Tan wire (yours is Green) and have 12V on the post, not the wire. That wire feeds power direct to the coil and back to the key
Maybe the new solenoid is bad, or its wired internally different
The Ah Ha moment. New solenoid but terminals are different.
Swap the Bat and Starter cables
The Ignition and Starter are and "should be" connected together. This way when the solenoid energizes the starter it also supplies full volts to the coil for starting. When key is released power is...
