8n running rough

Hi i recently got a 8n with front distributor ,it was not running at time so I ended up replacing plugs ,wires cap, points,and coil.
It is now running but misses with no change in engine when plug wires 3 or 4 removed . good spark and have checked timing twice. also did compression test with results 1-120 2-110 3-115 4-105 .could this be a valve issue or am I still looking for a electrical problem? also replaced manifold.would appreciate any ideas
 
RJM123, Check your firing order #1243,it easy to get #3 and #4 crossed up try swapping 3 and 4 wires.

I have checked wiring several times to be sure and am confident order is right
 
Just for the heck of it switch the #3 and #4 plug wire. Post back what happens. Seen many that because of the plug wire tube think it is right but be wrong. Also did you set the points at 0.015 like they should be?? Also maybe check the distributor and make sure the points open the same on all 4 lobes seen bad bushings cause a problem like that also
