OS 1.40 Needle Valves

[Ed Alt]

I seem to recall having a Fox 45-ish engine about 8 or 9 years ago that also 
had instructions on how to sand the taper on the needle valve in one place 
or another, depending on where it wanted to quit.  After going through this 
exercise and trying a different carb & needle valve that supposedly required 
less finish work from the owner, I turned it into a mini-fish habitat in a 
small NJ lake (just the motor, no airplane attached).  Never again!  They 
really need to stick with CL engines.
