260z misfire woes

[Markb]

Hi guys,

I have a UK spec 1978 260z 2+2.

A friend of mine took the car out one day and called me after parking it up for an hour saying he couldn't get it started as the battery had drained. We jump started the car but it was misfiring and barely running. I drove it home where it languished while life, work and other cars got in the way.

Recently, I got some enthusiasm to get the car back up and running. I've done the following with some significant improvement, but it's still misfiring:

New condenser

New spark plugs

New coil & ballast resistor

New points (in bad need of replacement)

Set timing

Checked Valves move up and down as they should

All HT leads are sending a spark to the plugs (although they don't look the freshest)

Dizzy cap looks fine and is clean inside

Rotor arm was a little bit burnt but I cleaned it up with some fine sand paper

I know I need to do a compression test (which I will be doing as soon as my compression tester gets here) but is there anything else I should check for? Are there any other common problems?

I really want to get it back up and running so all help greatly appreciated!

Mark
