Where is this check list?  I did find a value of 2500 ohms in the listing
for using the FI tester box on the head temp. sensor.  There is no outside
temperature correlation.

Yes, I have a new regulator that reads over 14v at the battery.

All 4 are firing according to my timing light and a visual check.

It's is.  The hose is older but I trimmed the ends so they are tight.  I did
notice the adjustment screw is not sealed so hopefully no one adjusted it.
