- Webra 145 AAR

[Rodney Tanner]

Jim, Lee or any one else using the Webra 145 AAR. . . .
I have a new engine that I am still running in - four clicks rich. It seems
to be venting a lot of raw fuel from the carb. Is that normal, given the
rich needle setting. I have checked the fuel lines etc. and everything seems
in order. . 
Any comments would be appreciated
