Hi, Ceslaw.

Are you talking degrees Celcius or Farenheit??
If C, we are very close.

1 x EGT or 02/ A/F- cencors in each runner would be the ultimate......

These are the results this far:

4- 5 cylinders showing 260- 270 deg C (5. has idle/CO screw out by 4 turns..)
1 running 165 deg C
2last show 80 deg C and clearly not firing.

For the two cold ones I have done all kind of testing; cleaning carb filter & idle jets. Checked fuel delivery and changed spark plugs.
The spark wires or terminals in dist. cap has to be dead? (I took it for granted this was 100% since everything worked so well before parking in the garage...)

The 5. with all those rounds out + the 165 C will be checked for leaks, theese are the same cylinders that showed vacum readings out of range, as well.

( To rule out another possible fault, I will check the valvetrain....)

So far, and brain boiling from frustration!
