I think it's a good idea to pull the plugs as the compression would put strain on the sprag which is a knoweth weakness if spun with a weak battery, it will cause more wear. I never had a carb monster but it was never a problem with the SS's that i had before because they have a low pressure electric fuel pump to prime the carbs. I think the vac pump on monsters is the main problem. Vacuum fuel taps are not ideal either if they only stay open when there's enough vacuum from the engine actually running.
