Hi to all, regarding my problems of strating my engine I have checked spark on every cyl. On number two (left side top) spark is genereted without problem but not on other three cyl. I think it' impossible 3 coils got broken in the same time! could be something broken or loosen under the flywheel? thanks to all<br />ciao<br />Lorenzo

Howdy, Ronco. It is uncommon to lose spark on three cylinders and not on the fourth, but I think your most likely suspect is a failure of the CD Ignition Unit (commonly called the powerpack). It has seperate circuits inside for each cylinder.<br /><br />Another possibility is the timer stator and charge coil assembly, under the flywheel.<br /><br />Good luck.<br /><br />Red sky at night. . .<br />JB :)

I think is something under the flywheel because just before the motor stopped (only when i reduced trottle) I heard something vibrating (very high freq). I'll try to check power pack with a tester after having read the manual...<br />Thank you
