I did take off the air cleaner and it seems I do have a fairly healthy squirt of gas when hitting the throttle. The fuel pump was not replaced to long ago...but no reason it can't be going bad I suppose. I did have it in the shop after relocating to Colorado for a tune up for altitude and asked to have it re-timed and new points. It still really bogs when hitting the throttle hard...mainly when cold and running with a little choke helps. Easy on the throttle and there is not as much noticeable hesitation. Does this still sound more carb/fuel related or should I still consider timing/spark may be off? Thanks again.
