Title: baby b 049
Post by: Bootlegger on June 17, 2020, 07:11:50 AM

  Got one that has been setting up for a couple of years, what is a good way to get it running without tearing it down?  Thanks

Here's a little video I made. It's the first thing I try before a tear down

u will be lucky if the reed is still flat, I run my racing reed valve engines once a year and have  to put new reeds in every year as the old ones are cupped and wont seal

Well I am fortunate enough to be in the same club as Al Heinrich, of Aerodyne fuels. Also Joey Mathison of speed fame. There've supplied me with fuel for a long time. I run 20, 25 or 30 percent nitro.  Al has his own synth/ castor blend. Joey has another blend that's similar to Brodak's 29 percent oil

If it is an older babe bee the reed is probably ok but may be stuck.  If the engine flips over good, you might just fuel it up and see what happens. I use 15% nitro and 18 to 20% oil - 1/2 castor. A little more oil is ok. I use TD heads and play with shims to get the run I like. I don’t have a tach so test runs and test flights are part of the fun for me.

It can’t hurt to take it apart and clean it good especially if you have access to gaskets, reeds and such. I toothpick a slight film of blue RTV around the edge of the tank and between the tank and case. Not really necessary if every thing fits good.
