Arrrrrgh... :evil:
Fired up Sami's J/P motor...Started nice...ran good, got the carb tweaked in to idle and rev clean...
Didn't take it over 4500rpm, just "burprd" it a few times...
And then all heck broke loose...
Govener rod started clicking and bouncing like the flyweights were hitting the govener rod (that's not supposed to do that...) :?
And before I could shut 'er down..BOOM... Blew the counterweight out the back... :shock:
Everything still spins free in there etc... Crank and cam look OK as well as valve train..I don't believe anything "locked up"...
Near as I can tell, the govener must have let loose and a piece got wedged between rod and counterweight on downstroke...and blew the counterweight out the back???
Rod is broke, but it happend at not much more than a fast idle ...not under power...Not sure that was the cause as much as collateral damage...
Motor was warm, but not "hot"..??
Sucks...Oh well pull out the back up and start over..
Open for trained eye observations..
