I just removed a 33cc Homelite chainsaw engine and want to convert it. I have a few questions for those who have already converted these. First, what is the black (plastic?) piec that fits over the top of the rear (clutch end) bearing. It has a tube with containing a rod with longitudinal ridges (like a long gear) that meshes with threads like a worm gear surrounding the clutch shaft. What is it? Can I cut the long part off that sticks out to the side?

Also, does anyone make a muffler or velocity stack that fits? I am pretty good with my hands but have no machine tools or metal fabrication experience. (Lots of woodworking)

I heard today that chainsaw engines don't take thrust forces well because they use needle bearings. Is this a problem for this engine?

Any help would be appreciated.
