Little tip to take doors off – just undo the securing nuts and kick the engine over – doors should just blow out nice and gentle – no need to “dig” them out
I did this on an engine last week when it refused to start and the door was stuck tight. However I forgot to take off the plug leads or leave the strap in place but loose. Typically as soon as I kicked it over it backfired into the crankcase on that side and the crankcase door was propelled across the driveway followed by a pleasing, if not rather worrying, explosion sound and a jet of flames and fuel 😕
All good fun.
