Ok.
Here is another problem on a different car. This is on the 510 wagon I drove back from Utah.
I only get about 25 mpg and you can tell it is running pretty rich.
I checked the vacuum, ignition timing and changed the coil. Still running rich. It has a stock looking hitachi carb, (rebuilt). It has an L18 in it.
When you come to a stop and start to go again, it has a stumble right off idle. That is the only time it acts up.
It idles fine, doesn't miss. It seems to be a little lacking on power though escpecially in the upper rpm range.
Is it possible the cam timing is off ?
