Anyone more than familiar with the Edson single lever engine controls, as in know them inside out?
Certainly sounds like a control issue to me. I'd second Faster's advice on tracking the problem, but I'm guessing you aren't getting quite enough transmission cable movement for your engine.It's in my "runaway diesel" thread, I am now 100% sure the issue is down to the control itself, and if you don't have a diesel you might not have looked in there.
- Run the engine in gear at cruising/high throttle, it'll be fine for a while.
- There is then a banging from the transmission, as if the cone in the gearbox is being slightly disengaged
- If you throttle back, it might slow the engine, you can go into neutral, back into gear and all is fine again (until next time)
- Alternatively, you can throttle back, nothing happens and if you happen to knock it out of gear, you then have an engine racing with no load at full throttle despite the lever being in the idle position.
- If you bang it back into gear (tried it today as a last resort) and waggle the lever around a bit, full throttle, idle, full throttle etc then you might get control back
There's a bunch of springs in the control mechanism and if the throttle lever actuator-thingy is disengaging from the controller's slide-thinghy.. Sorry, out of my league here!..What's still confusing me is why if the gear is partially disengaging does it also affect the throttle? I get that it is going to rev higher with less or no load, but why does throttle stop responding? If it was just jumping out of gear that would be one thing, but jumping out of gear and jamming the throttle wide open is another.
I already confirmed that the lever is operating things as it should at the engine end, the full throw of the lever on the transmission is used, as is the full travel of the throttle arm on the engine.Gears engage fully in both forward and reverse, and throttle gives me full range of motion too.
