No problem. Like you said, limited info (or miss-info), not being hands on and not knowing what the prior issues were makes it pretty much near impossible to even guess.
It's unbelievable how or why customers don't want to part with valuable information.
White wire - you are correct...
Sorry you were offended, I simply was agreeing when you were correct, and pointing out where you were wrong so that anyone following this would not be mislead.
You can check the resistance of a component that way, but not the voltage in and out as the component needs to be connected and...
Of course - there's always more to the story. I just don't get why people don't describe the entire history. No working multifunction tach, then you have no way of knowing if there are any check engine codes. "static check" ? what does that tell me? Are you back probing the connectors...
2003 engine. To properly diagnose you need the appropriate factory manual and test harness. The manual has a diagnostic flow chart to follow and instructions to properly test each component. Without them, you are simply guessing.
How are you testing voltages if you do not have the test...
Since it's a fairly new engine, why are you even fussing with it. It is the installing dealer's responsibility to set/confirm the WOT, and make sure the engine is propped correctly. You should have signed and received a PDI (Pre Delivery Inspection) form from the dealer confirming both of these.
What are the compression readings? If you are going to attempt to repair this engine yourself you should have a factory service manual and the proper test equipment to diagnose the engine's ignition system.
Small engine do come with props from the factory. In fact, all Suzuki's 30HP & below come with a prop. The op's prop is a 215mm x 180mm.
The only way to tell if the prop is correct is to connect a tachometer and see if the engine spins up to it's recommended maximum rated RPM.
Hardly worth...
Not really possible to diagnose properly via the internet. Too many possible scenarios for a check engine light. If the OP insists on repairing himself, the I suggest purchasing a factory service manual, the factory computer diagnostic system, and possibly the testing tools needed to properly...
