I started to take apart my homelite 150 to convert and decided that it looked like the carb was going to be mounted on the front of the engine and the muffler on the back. The muffler out the back didn't bother me, but having a carb on the front made me wonder. Since I didn't get very far on it I can add any advice. I did notice the left hand thread. Please let me know if you are successful, since I still have my chainsaw. Good Luck.
