hello, i finally got to try out my old auger. its a osciola magnum 3 3hp 33hp it has the older blue mora bit on it.. anyway it does work great i went through 5.5 inches of ice in less than a min. but at times it seemed that i have to put some pressure on it to cut a little faster. it cut smooth and shaved the ice. but i was thinking that maybee shimming the blades might make it cut faster. also it seemed to go faster if i sped up the rpm's by hand while cutting( pushing the throttle plate on carb). the blades are sharp. but maybee could use some new ones.. or is this auger usually on the slow side of hole cutting
