Whoopee

[Rcmaster199 at aol.com]

You know, I don't remember the 2 stroke gassies having the same issues. And 
they use oily fuel also except, much less oil. Could be the carb design we use 
vs the gassie carbs (Walbros mostly??). 

Has anyone used walbro in a real pattern engine and have it work? I had an 
MVVS 150 carbed with a Walbro a while back, but the engine was a dog (tried with 
a regular 2 stroke carb also) and never flew.
