I know that it is not recommended to shift gears on a slope. Can not say that it applies in your case with a runaway engine, but free wheeling on a slope is a big no-no.
Hi! Most engines Gas or diesel cannot run for a long time at more 30 deg.. You can damage your engine Some airplane engines can run all position .They have dry oil pan Oil cannot go in cylinders or pistons. Two cycles engines can run in all position .May be Some old JLO Rotax Yamaha snowmobile engines could be adapted at your Bcs. Be careful! Very steppy hills can be dangerous for you too Good Luck !

Another way to stop a runaway diesel is to engage the decompression lever ( if it has one ) . Hopefully I will never have to do that on my two-wheeler .
my recollection is that my old MB 280 diesel had an emergency shutoff that puts a metal plate over the air intake (downstream from the airfilter)...basically a "throttle plate" (even though the engine was FI)
You might be interested in air intake shut off valve by amot control - emergency shut down valve
the motor has hydraulic lifters and they should float before the engine blows up. /QUOTE]
Depending on the head configuration those floating valves may get to hit the piston's.
Many engines use an oil spray on the underside of the piston for cooling.
Positive air shut-offs work well.![]()
Hi! I find a special industrial engine ROBIN EH25D . This engine can run 100% duty or continue at incline 45 deg. The best I seen. Gas engine 8 hp Din This engine is on AGRIA two-wheels tractors and others industrial machinery. Good Luck ! Oldmech
