Husqvarna 545115301 Leaf Blower Engine Cylinder Genuine Original Equipment Manufacturer (OEM) Part

I had to replace the cylinder and piston on my Craftsman 25cc, 210 mph/450cfm blower (model 358.794650). This cylinder worked perfect, it was exactly what came off. As others have noted the intake and exhaust bolt holes are not threaded. I tapped mine with M6-1.0 and M5-0.8 and used new metric allen head bolts, same length of the ones that came out.

The aluminum cylinder took over a week to arrive, which is unusual for Amazon. (the reason for 4 star) It was exactly the right part to fix Poulan Pro bvm200vs. The leaf blower also had a hole in the piston, which I also replaced. A glitch in the repair is that the cylinder required the tapping of four holes. Two for the mounting of the muffler (metric M6-1.0) and two for the mounting of the carburator (metric M5-0.8). I did not have to use a tap drill as the holes were already close enough to 5mm for the exhaust and 4.2mm for the carb side. I took my time. I did have to chase the tapped holes for the carb with the original bolts as the bolts did not fit quite smoothly. The sizes were correct, but the bolts needed coaxing to fit. No such problem with the exhaust bolts fitting. I used ordinary 2 cycle oil to coat both cylinder wall, and piston skirt, and connecting rod pin bearings. It all worked out for me. Good luck on yours.

Just needed to tap four bolt holes working great
