I will be going to the Amain 30% nitro from our U.S. distributor after I finish off my 1.5 gallons. I tried the amain25% nitro. what I like about it is how clean it burns. Inside of engine was perfectly clean. I am really wondering knowing what I have learned from this site and yours,if 20% nitro is the way to go. I know there is all sorts of things that go to pipe temps,but if you could point me in the right direction It would be appreciated.

Acceptable pipe temps ? Have no idea , Hot enough to burn yoru hand
Check the inside recioever collett of your fly wheel , it may be worn and slipping , check the collet too , if it has scoring on it thats probably where its lagging .. The MG has plenty of instant snap.
If you run the 30 % A Main be sure to run 0.6 shims total. 7 mm restrictor
Run 1.1 springs. Answer rc shoes , 13 or 14 tooth depending ..
