no it doesnt work that way
If we place a spring under a piston of an engine then after suction stroke it raises up more fastly and we can get rid of starter motor is this possible?
Spring may be pushing one piston up, but another spring would have to be compressed for that piston to go down. For a single piston engine, the normal place for the engine to stop would be with the piston up (due to the spring) so you would first have to compress the spring to get the piston down for the first stroke. Need a bigger starter!!
What exactly are you attempting to accomplish here by doing this and BTW this wont work?
