Then there is fuel filters which can give variations if they are starting to
block up. I think there is a strainer in the tank itself.
If both those items check out there might be problems with IP itself>>>
Thanks for the suggestions - I replaced the end sockets on the linkages and
lubed everything, replace the fuel filters including the one in the bottom
of the fuel tank, even though it was perfectly clean. No algae was found
either.
As far as the IP being a problem - I assume they can work fine 99.9% of the
time and act odd the rest of the time? How would the IP be checked? I know
of a competent diesel shop which should be able to check-out the IP. Any
idea what that's called? A IP tuneup perhaps?
I must admit I haven't spent any time trying to learn how the IP works - I
know it pumps fuel at high pressure to each cylinder in turn - and the
timing is adjusted by rocking the IP toward or away from the engine. After
rebuilding the engine I adjusted the IP because it was smoking excessively.
It was a trial and error thing -
Thanks for your suggestions!
