Title: Today my 5-29 fuel let me down!!!!
Post by: frank mccune on March 28, 2020, 04:59:26 PM

           Hello All:

           I was flying my older OS .35S-ST .46 hybrid and it ran very poorly on my usual 5-29 fuel.  It usually runs very well on this mix.  The plot now thickens.  On the first run off the day, I accidentally ran a tank of 11-11-5 through the engine and the engine ran perfectly!  The next 3 flights on the 5-29 fuel were awful.  The engine was difficult to needle and it ran very inconsistently.  Did the first tank of fuel change anything in the engine?

          My flying mate insisted that I switch to an LA .46 and stop messing with these old engines.  He talked me into that idea!!! It is past time that I get with modern engines!!!!  I have seen those OS LA engines run and they run very well!! Easy to start and CONSISTANT!

           Now if only Rossi would make a .40 Stunt engine! Lol

                                                                                                 Be Well,

          Hi John:

          It is so fresh that it should have its face slapped!
