Ok;

My final experiment becasue I have a perfect transition and a VERY smooth low end idle. The high end is unchanged.

Motor;
Homey 45cc
glow to sparkplug adaptor
4 stroke glow plug powered all the time.
A walbro 499 carb (I believe cant remember the exact number but I can get it if anyone cares)
The fuel I used was 5 ounces methanol 5 ounces gasoline 3/4 of an ounce of 35% nitro/castor. The nitro I purchase was from the LHS and it was SIG champion fuel.

The test went.
Fueled up plane
Primed it about 6 flips (wide open throttle with my thumb over the carb)
Plugged in glow plug
1 flip backwards and it fired right up and ran.
I needed to lean the carb out on the high end.

Smooth transition and a great low end idle (I will try and get rpm data if the plane lives through the day)
The Nitro as mentioned many times help ALOT.

Edit;
I could not take it so I had to do RPM data
High end 7500 rpm
Low end it will idle down to 1500 pretty easy but I like it at 1850.

Good luck and have fun experimenting.

I found my methanol at a local speed shop for 2.85 a gallon.
