after being told by several rotary professionals that my new motor was bad, we finally disassembled the block last night.
Upon inspection, the rotors, housings, and apex seals looked like new. it seems that the carburetor I paid good money to have built was having issues with secondary fuel flow under load.
pretty frustrating after all this time and now more money that will be put into its new buildup..but it will be well worth it when we're done. thanks again @eddyrenown
