Bill,
It was a day and night difference. No more deadsticks, and a great running little engine. There are replacement carbs, namely the carb used on the G23, but I wouldn't do that unless you really have to. This is a quote from RCIGN1 on how to set the carb on the G26:

"The low is too rich and is affecting the high...Typical low setting is about 1 1/3 to 1 1/2, then with the low leaner you will have to re set the high...
The carb on the G26 is pretty big for the size of the engine and needs to be set a little differently..Open both about 2 turns...Set the idle speed at about 2000 rpm and slowly lean out the needle.(If it won't idle at 2000 it's way rich on the low needle.)..The idle speed will increase..Re set to 2000 and continue leaning..When the speed no longer increase...Go back and try the transition..If not good slowly open the low needle a little at a time until the transition is good, and re set the high...I think you will find both needles open about 1 1/3 to 1 1/2 after adjusting this way...A 16-8 and an 18-6 will both turn about the same, but the 18-6 will pull harder and fly the plane slower..Depends on what you want...A non restrictive noisy exhaust diverter will give you about more rpm..It should idle at 1800 when correctly set.... "
