!988 4AF Idles rough and misses through driving

#1
Hi all:

I recently got a 1988 Corolla for my daughter and since day one it has this stutter at idle...I've changed ignition cap/rotor/wires, rebuilt carb, traced all vacuum lines, replaced head gasket (had a burnt one on!), adjusted timing, and STILL misses at idle and throughout driving range. Today I checked the resistance at the coil and got a reading of 1.7 ohms at the primary, secondary circuit reads good...this is just .2 ohms over specified limit of 1.5 ohms ( says it should be 1.3 to 1.5)...do I need to replace this coil for this over-reading? If not, any ideas as to what I should check next? All cylinders measure good compression...the one thing I have not checked is the valve shims...I'm baffled!
