OS.46 AX Zero nitro
 

Would the os.46AX run on zero nitro? what tuning required?

G'day Mate,
OS state in the maual, that, "for best performance use 5 to 20% nitro", but it does not say the motor won't run without nitro, so run it & tune it as required, it will be fine, but you may find your tuning range will be a bit narrow, & your idle speed may not be as low.

Have no problems with a os46fx on NO nitro. Have been using on for years on straight fuel. No prob with tuning and sitll get a good idle.

Cheers

Have been using only KLOTZ for the past 20 years with no problems.

G'day Mate,
I use Coolpower only, & no castor, but if you want more lean run protection, use some castor oil, but I find it leaves all sorts of nasty black crap on & in your motor, so I have not used castor for many years.

i saw a post long time ago but could not find if somebody used a medical castor oil, is this possible?
