backfire thru top carb.switched coils and plugs and plug wires and CARBS around still pops. difficult to start. when i advance the timing a bit it cranks but its still not completely smooth.runs rough at idle in yard test but does quite a bit better when i rev it up some. could it be a reed or something else?
