Or maybe oven cleaner, works on the outside very well should work on the inside as well.

  Hey Bill,

   

  How are you doing?

   

  Good question.  I meant to put that info in the original message.  I'm not sure just how many flights were on the pipe.  The way we like to put in these parts; is "there were a ton of flights on it".   I'll be a little more specific, at least two solid years.  I bought the engine and pipe from Earl at the beginning of 2004 and flew it all last season.  Earl bought it brand new in late 2002 or early 2003, I'm not sure.  But he put some serious time on it in 2003 in preparation for the 2003 Nats.  He then continued to use it for the remainder of 2003.  So, how many flights is that?  Your guess is as good as mine, has to well over 500, probably a whole lot more, I really don't know.

   

  Since I started this thread I've been thinking a lot about solvents and pipes, particularly the flow capacity of pipes.  I think I can make a strong recommendation to everyone now and that is; baseline the flow capacity of your pipe before you ever use it.  This can be done very simply by filling it up with water and then timing how long it takes to empty itself.  Do this several times, up to a dozen, to get an average.  Record this information in a safe place so when you think your engines performance is beginning to wane, do a flow test again and match the new rates against the old.  This is cheap, easy way to know what you're dealing with.  Kind'a like what the big boys do to know what the flow capacity of their automotive cylinder heads is.

   

  As far as solvents, last night I soaked the pipe in water.  Yep, another Earl idea.  I tell you when the man speaks, I listen.  You never know, it just might work. Anyhow today (it's raining outside anyway, so what else is there to do) I plan to flush it with hot soapy water and watch to see what kind of crud comes out.  Next, on the solvent list is; Mineral Spirits, then maybe your Gumout, or Bob Richards paint remover, or ..

   

  See you at the Beach!

  Buff (and others who have had the same problem)
  About how many flights did it take to get the pipe blockage that you folks are talking about?  Obviously, it announces itself by degrading engine performance, and I was curious about when to start looking for the problem.  One of my Hatori pipes had a lot of crud on the outside, and I cleaned it with some Airplane Cleaner that I picked up at Advanced Auto Parts.  It took several applications, but did a fair job of cleaning.  But--that's not the same as the inside of the pipe.  When I was building engines, I had a 5 gallon pail of carburetor cleaner and I'm wondering if that stuff would do any good.  It sure removed all the crud from a carburetor; while the race engines never got all that dirty, I did do other stuff besides, and I saw the carb cleaner work miracles.

  P.S. Buff:  See you at Myrtle Beach!

  Hi Steve,

   

  You're not too late.  I had the pipe in the PP for 24 hours with no ill effects.  It did clean some carbon, as seen by chunks of carbon being flushed out.  But did it clean it thoroughly?  I guess the engine will tell me next time out.  Or, though I'm not quite ready for this; perform an autopsy on the pipe.

  Be careful with the Purple Power on aluminum. If it's the same stuff I'm thinking of, made by Castrol, I used some to clean my motorcycle wheel and it pitted the aluminum rim! Hope this message is not too late.
