914 Woes...
Hi.
I have a MTO Sport gyrocopter of 2007 vintage (635 hours).
Just young enough to have the new crankcase and the red ignition modules.
This engine has served me well for around 100 hours. Never a problem, smooth running.
But just a few weeks after a nice evening flight I wanted another.
And the engine was dead - completely. Scratching my head... From smooth to dead...
After some troubleshooting - lots of fuel coming to the carb bowl (just tested one).
Nothing wrong with the grounding "mag" swithces - and wire all the way back to the ignition modules ok.
Then I ohm'ed the different coils - all values were in range. Then it had to be the 2007 ignition modules, right?
After I tested the coils and plugged it all together (again) the engine started up. Strange - some bad connection...?
But now it runs rough above 3200-3700 RPM... like the propeller is out of balance - in a strange way.
New modules - nothing changed. Oops - two spark plug caps weren't fully inserted - just looked like they were.
Nothing changed. Newly cleaned and oiled air filter taken off - nothing changed. Now I am at a loss.
(since the engine wouldn't start, I changed the oil and coolant hoses. That's another beehive by itself)
I haven't touched the well-balanced carbs at all. Except having had the bowl off one to check fuel flow.
What to do now?
Cheers
Erik
