My engine has just started hesitating and stuttering. Hard to get up to speed. Here at the details: '68 F engine great compression, just checked, plugs look good new non-USA distributor w/ points and condensor new fuel filter, just re-checked to see that it's clean new fuel pump, healthy flow at carb and ... I just replaced the carb with my spare carb to see if it would make the stuttering go away. It did not! So, what's left? All I can think of is the coil or the condensor. Would a bad coil or condensor cause the engine to stutter at higher speeds? Note that the engine idles just fine, purrs like a kitten. I'm stumped.
