You can also enlarge the gap of the spark plug to 1cm which corresponds to the normal condition in the engine to check it. Strong ignition can bridge up to 1,5cm.
But somehow this sounds more like faulty timing to me.
You really only changed oil for the right oil in the right amount? And around 1l oil came out?

Okay thanks Peter, I'll try to do that measurement this week. How would I check for a timing issue?

And yes it ran fine and then shut off after changing oil. Around 1L came out and I filled it up to right around the middle of the sight glass

Thanks, Jandro

Hey Jandro,

Still haven't figured it out, but haven't been working on it lately since I'm not sure where to go. If you figure out your issue, please report back and let me know what your issue was.

Thanks!

Sorry to answer this late, I have not yet have to rebuild this engine (and glad so) therefore I had to search a little.
Page 148 of the Repair manual ( e.g. from here https://drive.google.com/folderview?...ms&usp=sharing) shows how to set/check timing chain (when installing). The repair manual also has a checklist in case of particular faults, something to look into as well maybe.
I was surprised to not find anything particular on the ignition timing. This means it is completely handled by the flywheel and the ECU, nothing to check/set there.
This triggered another thought. The various sensors (see e.g. page 2 of https://drive.google.com/drive/folde...W1aYm9qX0o4MWM) together determine timing and injection. Maybe wiring got bad or sensors are failing?

I'm mostly curious what can go wrong changing oil. It can be unrelated with freak timing but most often it's not.

Following this, it will be interesting to get the answer
