given by the information, your LSN is very rich, which would almost cause it to flood out, so you are having to compensate by opening up the idle gap. factory settings are rich settings for break in not running settings, you will have to lean both needles out to get performance and correct running. common signs of loss of compression is flame outs and inability to start the engine while its warm, but once its cold the metals shrink giving it compression to start again. if you want to check to get a better gauge you can pull the piston and sleeve and see how far the piston goes into the sleeve in the correct orientation as if it was installed on the engine. if it goes past the top, its about done for, if its still down in the sleeve, you still have life left.
