    Hello all! I'm new to the world of MB. I got my first build finished and running. But produces quite a bit of smoke? Is that normal during break in? Sounds fine and has plenty of power. Thanks!

    if your running a break in mix (lean on gas) like 16: or 20:1 you are going to get some smoke. research break in oil to fuel mix, usually nobody runs 16:1. more like 20:1 or even higher.

    I'm breaking in a new jug and rings with opti-2 at a 100:1 to see what happens.I've read good things, but if it doen't work out a new jug and rings will run me $20.
