my mg66 is going in my mbx6 buggy
Sweet

Try and get 10 tanks through the MG66 with the foiled head, and it should be loose enough to perform pretty good. I reckon mine has taken just on 4 litres to come right up to speed. It's pretty well as lean as I can go on the top without getting lean bog now (pretty well right on 1/4 turn in from flush), and it's haulin butt

Hi Giz - just a query on the alloy shim you took out ? The break in shim comes in the box with the motor (a .3mm or .2mm brass shim - can't remember which). It is not fitted at the factory to my knowledge. The .3mm alloy shim and the 2 x thin .1mm brass shims should stay in the motor.
If you took the alloy out, you will only have .5mm total shim including head button - might be a little much compression running 25% ?
