Webra Stainless Bearings

[Rcmaster199 at aol.com]

The running procedure is very simple; rich, both at idle and full. As rich  
as the engine will allow. It needs a very hot plug and tends to eat these more  
often than you would think. If you found yourself leaning the mixture out too 
 often, then the likely cause is the plug. I run F's in mine and 15-20% 
nitro. It  runs rich enough to see a solid smoke trail; then I know the engine is 
happy. 
 
It only needs a handful of lean runs to blow the bearing
 
Recent experiments with a Perry Pump Carb indicate the engine has a bunch  
more output than we are tapping. The Perry's throat diameter is .375 vs .355 for 
 the stock throat in either the MC or the TN carb. (I bushed the venturi down 
to  .375, BTW).  So far the Perry's settings seem to be less sensitive to  
weather than the TN's. Experiments are continuing.
 
Good luck

400 Plus on the standard.....youve got to be kidding me.
 
My running procedures must suck, best I ever got was around 150.
 
Thanks for the info.

Just curious if anyone has been running the stainless bearings now  available 
for the Webra and how they are working out. 
Thanks 
Brian


Brian a friend is running it in his Webra and reports identical  performance. 
Has not run long enough yet to determine life, but if the  standard steel 
bearing is any indication with its 400 plus flights life  span, the stainless 
should have a much longer life. Probably  longer than the engine's  life.
