83.5 Westy Water-cooled. From a cold start she will run great
for the first few minutes. As soon as she gets warm everything turns to
worms. Idle goes nuts, power vanishes, stagger, stagger, stall dead....
Let her cool off for a while and again she runs great until she warms
up. Then the cycle repeats.
        I am about to commence troubleshooting in the next few days. I
have a Bentley, a Haynes, a good Voltmeter and a lot of hope but near
zero knowledge. Any hints of where to look and what to look for would be
VASTLY appreciated.
