Hi Vm ,Tyler and Speedy

The problem is if the standard specs are 16 to 1 and you run 25 to 1 the fuel mix will be overly rich as the
carby is set for 16 to 1.

I ran 25 to 1 on my Pope but it sounded like it's over fuelling down low ,I was going to try 20 to 1 next time with
good 2 stroke oil but not with fully synthetic oil.

16 to 1 is 473.176 ml to 7,570.816 ml

Cheers
Max.
