Has any one ever made a cold air intake for a husler??? Would it even be worth the throuble?? Mine is a 18h.p. kohler-4 stroke-single cylinder, the motor draws air into the shroud to cool the it . the air filtre takes air from the shroud to feed the carb. When I first got the unit, it had a pipe sticking up in the air with a little mower muffler on it, no hot air box. I called R&R to price a new one "I don't think so$$$$" I don't know how I got the idea, but I took a old snowmobile muffler and cut and weld and cut and weld,you get the idea!!! The new mufler comes through the back mesh witch was aready cut. I reset the carb and I was shocked, huge power gain and I consider it to be very quiet!!! I also took heavy sheet rubber and a air duct to blow hot air out the back.
