Question-OS140FI

[davel322 at comcast.net]

Frans,

I had an OS104EFI behave in a like manner (albeit, not after a period of 
storage).  Changing the injector fixed the problem.  I suppose it is possible 
that the injector may be partially clogged with congealed oil and restricting 
the fuel flow at full throttle - in which case soaking the injector in fuel 
might help.

Good luck,

Dave Lockhart
