Speaking of Petteroids, who's importing them these days? 

Seems a few folks are importing Listeroids, but I haven't seen anyone mention the Petteroids.  I have a freind who needs more reliable backup power for his server-farm than a few deep cycle batteries and UPSs can provide.  'Least that's the story he tells.  I think he just wants an engine to play with.

Any outboard motorboaters here familiar with a product called Seafoam used for decarboning outboards?  I read about it on the forums at iboats.com and gave it a try on my old Evinrude and it worked like everybody said.  Spray the stuff in the carb throat of a warm engine at idle until the engine floods out, then wait 1/2 hour or so during which you can remove plugs and spray more down plug hole if you're really anal about it.  Then start engine and all kinds of black carbon particles spew out the exhaust as the badly flooded engine coughs to life emitting clouds of white smoke. 

The product appears to be a mixture of something like gasoline or toluene or hexane and light oil which might be castor oil.  Makes a nice flame-thrower when sprayed over the flame from a zippo lighter (Do not attempt.  Professional driver, closed course.) 

Seems like something like this might work for a diesel, too.  Spray it down the intake throat, close the rack and restrict intake air to prevent run-away and continue spraying as choked engine slowlly dies for lack of oxygen.  Then restart after a half-hour or so.  You can also remove the plug in the pre-chamber and sluice it down directly.  At least on 2-stroke outboards that have carbon problems, this procedure works well and really improves starting/idling and slow speed operation where carbon fouling is often a problem.  With a diesel, who knows?
