[TR] Rough Running TR4 - Update

[pbrandsema at triad.rr.com]

First, thanks to everyone who has sent me replies, this list is full of great people!

After checking fuel pump and ignition last night, this is what I've found so far:

I've ruled out fuel, getting plenty of that (had to disconnect fuel line in order to crank engine).  Checked all plugs for spark, it was there, but very weak, so that seems to be the direction to look further.  Distributer cap new last year, replaced with plug in type.  I did notice that the coil to rotor contact, when the cap was off, was off center due to the spring load.  I'm assuming that when the cap is tight on that the contact centers itself.  Now I have to determine whether it's the pertronix or the coil.  Any suggestions?

I also did a compression check, just to rule out any possibility of a more serious condition.  All cylinders came in around 180 psi.  I haven't checked what normal should be, but that number seems good.

Thanks
Paul
