They both ran fine with only minor adjustments. Then all at once I started the VF3 and when we went to clear it before takeoff it wouldn't come up and was throwing some serious smoke. I turned the HSN in and it seemed to be OK.
First thing I'm going to do is change the plug. I'll put in a K&B1L.
Scott had a problem with a newly purchased plane. The oils seemed to be incompatable and created a string-like substance that gummed up the works. I was feeling around to see if anyone had a problem changing from Ritches Brew to Cool Power.

What say you?
