I'll be sending you a muffler that works great for converting along with the Homelite 30cc. It's a nice little square one and fits the Homelite 30cc. You should wait for it to arrive. I carefully clamp them in a vice, and then using a sharp screw driver, I bit by bit open up the crimp that holds the muffler halves together. When you have worked your way around and gotten the crimp open enough, the muffler will come apart. Do it a little at a time so that you don't damage the muffler. Then when you take everything out from inside the muffler except the two bolt spacers that keep the muffler from crushing when the bolts are tightened, you can put it back together. Put it back in a vise, and use a hammer and a punch to little by little re-close that crimp. I usually coat the halves with JB Weld before crimping them back together to assure they don't leak and make a mess on the front of the airplane. Then you can make your outlet holes, prepare your outlet tubes, and weld them in. Done deal...
