ive just gotten an really nice 88 rx7 13b gx. 5 speed, 78k miles. the problem is its been sitting for 4 years since the death of a family member. so, coolant leak fixed, brakes unseized, etc... but, it wont run. it fires right up, and runs up to 2k on the tach, then dies instantly, no sputtering. i discovered that the butterfly on the intake was frozen (not the throttle) and freed that, changed the fuel filter, put in a little fresh gas, and even put some 20w 50 in the leading plug holes, but still wont run... any advice? anyone?
