hey guys,
Adam here, been reading this thread with great interest! I just got myself a Hong Nor X1CRT with a GO 25, which I'm in the proces of breaking in (only been through 5 tanks). Is 10 tanks safe to start leaning out the mixture?

just wanted to say hi to everyone and thanks for all the useful info!

one quick question - I have 20% and 25% nitro - can i use either?
can they be mixed? would this produce 22.5% nitro?

aplogies if any of those are silly questions

cheers!
