[C320-list] Fwd: Engine problems

[Karl Mielenhausen _/)]

John,

Please let us know what you actually find out... it would make a good  
article for the technical section of Mainsheet.

I would have thought about something on the shaft or prop first also,  
especially if the engine runs OK out of gear. Of course that could just be  
due to less hp demand (load).
What was your engine water temp doing through all of this? If it was high  
and you could not develop full power and had a rough idle, that might  
point to a clogged injector.

I'd bet on fuel contamination, however, especially that was the "last  
thing that changed" in your cause and effect analysis. The fill-up may  
have added water or algae or stirred something up in the tank (less  
likely).

Over the past 2 years, I've been using a product called Algae-X and have  
been quite satisfied.

It has the added advantage of adding lubricity to the fuel. This can be  
important if you are using ultra-low sulfur fuel.

Now I am trying a less expensive and more readily available product called  
Diesel Kleen (Auto stores, Walmart, etc).

and also adding the very popular Starbrite Biocide

Together they should do the same job.

Best regards....
