I was running my excellent 3 cylinder gas OC46 yesterday. Never have any trouble with it. Under load I was lifting a bucket of gravel. I adjusted the throttle up a bit to add hydraulic pressure. Then the engine suddenly raced, as if the governor did not kick-in, and died immediately, just as I leapt to take the throttle lever down to zero. It raced for a matter of not even two seconds before dying!
I have not been able to start it since, even though it all sounds fine, and turns over fine.
I have checked the fuel so far. That's getting through OK.
Any ideas before I take the hood off and check for sparks?
Thanks. Chris
Hi Chris, check the governor and magneto drive, something may have broken there, Bob
I was gonna say it has to be something that happened suddenly - like jumping timing - but I don't see how that could happen with timing gears. Unless that engine has a timing chain instead of gears. I am not real familiar with that series of Hercules.
Yeah, better check governor. There's no magnetos on those. Distributor/coil etc.
Wonder if it could the coil, but loading the engine would not affect the coil, surely.
Will check for spark first.
